add default configuration form to Config page, fix the link to add a new view, and minor pareview fixes, particularly short syntax for arrays

Charts can accept 'create secondary y-axis' option from Chart Attachment displays. This commit also removes a bug in Charts Google that led to duplicate empty fields.

This reverts commit 31a47799.

Initial commit of the new 2.x branch of Charts. Full porting to D7, new Google Charts and Highcharts support. Expanded docs and API support.

* Initial Port to Drupal 7

* Functions moved from one file to other in order to improve performance

* [#461660] by kenorb and brmassa: 'set default settings for charts' instead of 'access administration pages' access

* charts.admin.inc will deal with admin pages and form generation while charts.inc will deal only with common chart building routines
* _charts_settings() should be used instead variable_get('charts_settings') because it might initialize null variables
* _charts_settings_form() is now a separate function that might be used when a module wants to set custom settings for a given chart instead the defaults

* If there is no default chart provider or chart type select, now uses the first one enabled by default.

API Changes:
* The new hook_chart_types() set new chart types (like "Vertical Bar 3D")
* The '#types' on hook_charts_info() now only list the chart type code.

* #426438 by brmassa: If the chart data is missing the provider file, it must not end as an error

Internal:
* 0 errors or warnings on Coder module

* #333918 by brmassa: Fatal error: Call to undefined function: () in /var/www/.../charts/charts.module on line 79

* #323881 by Pasqualle and brmassa: Views 2 integration

* Alert users when the Charts module default settings were not yet set.

* Dont crash or point errors when the default plugin was not yet defined

* Dont crash or point errors when the default plugin was not yet defined

* Some modifications on hook_charts_info. now it returns all info without the need of an operator

* hook_chartsapi renamed to hook_charts_render

* hook_chartsinfo renamed to hook_charts_info

* Converting all files to UNIX end-of-file

* Some Drupal code compliance fixes

* Apply the correct color value intochart data

* Color module integrated and some fine tunning

* Simplified the settings page

* Drupal 6.2 changed the access rules. Fixed

* The new color palette is now merged to the chart data depending on what type of chart it it (generally, it adds the default color to series, but in case its a Pie Chart, it uses the palette on values)

* New menu description for Settings page

Misc:
* Testing environment page disabled for a while

* _charts_series_values() moved from charts.inc to charts.module

Misc:
* charts_chart() dont need the chart plugin as the first argument, since it will be given using the $chart array or thru settings

* Now settings options about series are loaded. So its possible to set default color for series.

* charts_chart() function now works fine

* implementation of hook_requirements() to alert users that he/she didnt installed any chart provider module
