Some big updates

Hey,

I made a whole bunch of updates to the module for a client and wanted to post back the changes if you would like to integrate them.

The changes include:

• Added a simple helper for making Get Satisfaction API calls
• Split the settings into multiple pages: (General, Widgets, Feedback Tab widget, Feedback page widget)
• Added functionality for having settings that depend on a particular plan
• Added some settings that the module did not support but the widgets do
• Feedback page now has its own settings and optionally accepts a path and title which will cause an actual menu callback to be enabled (for people who don't want to use the filter).
• Reorganized some code to suit my style, sorry :)
• Implemented hook_block and added a block version of the feedback page.
• Changed how settings are saved: there is now one variable per widget type.
• Moved admin forms to getsatisfaction.admin.inc

I know its a lot to digest and test. Please let me know if I can help debug or fix any issues that come up.
