Issue #2046965 by martinjbaker, paravibe, danylevskyi: Typo in user map and node map admin interface

It's pretty obviously flawed, but everything is up and running except association.

It doesn't really make much sense under D7 anyway, taxonomy doesn't associate with nodes the way it did before,
it's all field based now.

Definately not done but it's helping with testing other parts of the system.

fix up gmap_location a bit.
change an old update to point to the issue queue -- not worth rewriting for d7.

Rename permissions:
"show node map" -> "view node map"
"show user map" -> "view user map"
"user locations" -> "view user location details"

Remove 'set user location' permission, it's a leftover from the days that GMap used to be responsible for user locations.

Fix variable usage bug. It hasn't caused problems because the backwards compatibility variables are still being used as a fallback.

* Allow multiple locations for users and nodes.
* Fix marker titles and give them sane values.
* Add offset to make markers with multiple images work as expected.
* Rewrite gmap_location_author_block_view() to work similar to gmap_location_block_view().
* Remove hardcoded 'gmap_location_authorblock' mapid to match the behavior of the node block. (Reassign it in the macro if you need it.)

Fix #345269, noticed while helping George2 in IRC: Call node_view() instead of theme('node') to make stuff like CCK fields get output correctly in node markers.

#336995, reported by skyredwang: Disable caching for gmap_location blocks, because they do dynamic things.

#279049 reported by tormi: Use a valid variable for the author map marker. (You can now choose a marker by going to "configure" for the author map block.)

Fix minor issue with node type names. (This technically prevents XSS with content type names, but if you're giving out the ability to create / edit content types to people you don't trust, you have much bigger problems.)
