It's better to use VBR for local recordings, so this option should be
nice for people who want to do that.

Sometimes certain drivers do not have the capability required to
initialize the graphics subsystem (mesa currently, for example).
Instead of saying "your hardware is too old", state that the drivers may
also be at fault.

If the data isn't manually cleared it will accumulate, and cause json
errors if update check/log return is queried more than once

The informative text is meant to be additional information, not the main
information.  If you use informative text without using regular text, it
causes the message box to get all squishy.

Qt doesn't like to use size_t anywhere.

Remove failed test and add other Messagebox to correct Text with Language support

Add Title again -,-

Summary:
- Prefix all graphics subsystem names with gs_ or GS_
- Unsquish funciton names (for example _setfloat to _set_float)
- Changed create functions to be more consistent with the rest of the
  API elsewhere.  For exmaple, instead of
  gs_create_texture/gs_texture_destroy, it's now
  gs_texture_create/gs_texture_destroy
- Renamed gs_stencil_op enum to gs_stencil_op_type

Instead of having functions like obs_signal_handler() that can fail to
properly specify their actual intent in the name (does it signal a
handler, or does it return a signal handler?), always prefix functions
that are meant to get information with 'get' to make its functionality
more explicit.

API Removed:
- graphics_t obs_graphics();
Replaced With:
- void obs_enter_graphics();
- void obs_leave_graphics();

Description:
  obs_graphics() was somewhat of a pointless function.  The only time
that it was ever necessary was to pass it as a parameter to
gs_entercontext() followed by a subsequent gs_leavecontext() call after
that.  So, I felt that it made a bit more sense just to implement
obs_enter_graphics() and obs_leave_graphics() functions to do the exact
same thing without having to repeat that code.  There's really no need
to ever "hold" the graphics pointer, though I suppose that could change
in the future so having a similar function come back isn't out of the
question.

Still, this at least reduces the amount of unnecessary repeated code for
the time being.

Renamed:                         To:
-----------------------------------------------------------
obs_sceneitem_getscene           obs_sceneitem_get_scene
obs_sceneitem_getsource          obs_sceneitem_get_source
obs_sceneitem_setpos             obs_sceneitem_set_pos

Changed:
- obs_source_gettype
To:
- enum obs_source_type obs_source_get_type(obs_source_t source);
- const char *obs_source_get_id(obs_source_t source);

This function was inconsistent for a number of reasons.  First, it
returns both the ID and the type of source (input/transition/filter),
which is inconsistent with the name of "get type".  Secondly, the
'squishy' naming convention which has just turned out to be bad
practice and causes inconsistencies.  So it's now replaced with two
functions that just return the type and the ID.

Prefix with obs_ for the sake of consistency

Renamed enums:
- order_movement (now obs_order_movement)

Affected functions:
- obs_source_filter_setorder
- obs_sceneitem_setorder

Change obs_sceneitem_info structure to obs_transform_info - this
structure will not just be used with scene items in the future.

The OBSBasic UI will now allow the use of a subdirectory of the user
application data directory for third-party plugins.  Though I'm not
entirely sure if this ideal or not.  Regardless, this is one of the
first (of many) steps towards a plugin manager.

On windows, this is %appdata%/obs-studio/plugins
On linux, this is ~/.obs-studio/plugins
On mac, this is ~/Library/Application Support/obs-sudio/plugins

Changed API:
- char *obs_find_plugin_file(const char *sub_path);

  Changed to: char *obs_module_file(const char *file);

  Cahnge it so you no longer need to specify a sub-path such as:
  obs_find_plugin_file("module_name/file.ext")

  Instead, now automatically handle the module data path so all you need
  to do is:
  obs_module_file("file.ext")

- int obs_load_module(const char *name);

  Changed to: int obs_open_module(obs_module_t *module,
                                  const char *path,
                                  const char *data_path);
              bool obs_init_module(obs_module_t module);

  Change the module loading API so that if the front-end chooses, it can
  load modules directly from a specified path, and associate a data
  directory with it on the spot.

  The module will not be initialized immediately; obs_init_module must
  be called on the module pointer in order to fully initialize the
  module.  This is done so a module can be disabled by the front-end if
  the it so chooses.

New API:
- void obs_add_module_path(const char *bin, const char *data);

  These functions allow you to specify new module search paths to add,
  and allow you to search through them, or optionally just load all
  modules from them.  If the string %module% is included, it will
  replace it with the module's name when that string is used as a
  lookup.  Data paths are now directly added to the module's internal
  storage structure, and when obs_find_module_file is used, it will look
  up the pointer to the obs_module structure and get its data directory
  that way.

  Example:
  obs_add_module_path("/opt/obs/my-modules/%module%/bin",
                      "/opt/obs/my-modules/%module%/data");

  This would cause it to additionally look for the binary of a
  hypthetical module named "foo" at /opt/obs/my-modules/foo/bin/foo.so
  (or libfoo.so), and then look for the data in
  /opt/obs/my-modules/foo/data.

  This gives the front-end more flexibility for handling third-party
  plugin modules, or handling all plugin modules in a custom way.

- void obs_find_modules(obs_find_module_callback_t callback, void
                        *param);

  This searches the existing paths for modules and calls the callback
  function when any are found.  Useful for plugin management and custom
  handling of the paths by the front-end if desired.

- void obs_load_all_modules(void);

  Search through the paths and both loads and initializes all modules
  automatically without custom handling.

- void obs_enum_modules(obs_enum_module_callback_t callback,
                        void *param);

  Enumerates currently opened modules.

This refactors the sub-window code a bit so that instead of deleting the
window pointers, it calls QWidget::close() on them to safely trigger a
normal close on them instead (which will also delete them).
Moves setting the DeleteOnClose flag from inside of the Dialog classes
into the OBSBasic class, to make that behaviour more obvious.

Changed API functions:
libobs: obs_reset_video

Before, video initialization returned a boolean, but "failed" is too
little information, if it fails due to lack of device capabilities or
bad video device parameters, the front-end needs to know that.

The OBS Basic UI has also been updated to reflect this API change.

Fix bug where updates for windows would check for mac updates and vise
versa.

(I am ashamed)

There's no need to initialize the map value to 0.  What was happening is
that obs_scene_add was adding a ref to a non-existent value, which
simply created it and added 1, which is perfectly fine.  Then,
obs_add_source would set the ref to 0, overwriting the existing value.

So this meant that if you didn't call them in the right order, it
wouldn't work properly, and would break, which was pretty stupid.

Turns out that if you access a map value that doesn't exist, it'll
create one with the default constructor of that type.  In this case, int
will initialize to 0, which was exactly what we wanted in the first
place, and defeats the purpose of even needing to initialize the value
to 0.  So, there's no need to manually set it to 0 in
OBSBasic::SourceAdded, or worry about the order in which the functions
are called.

Just goes to show you have to be careful with reference counting.

Fixes #177

Instead, just use separate version and download entries.
