Set custom theme earlier in request cycle (hook_init), less chance that theme_init will be called before us.

Improved _fb_handling_form test to work even when form_token not present, as can be the case when user is not logged in.

Moved admin sidebar to right side of page, because absolute position no longer allowed.  Also, don't show picture when facebook user id not known.

now handling nested fb_init_path calls, and not logging is as infinite session when user visits canvas page.

Now using php4 client libraries, even if running php5.  This keeps support for php4, while avoiding uncaught exception problems.

Now using fb_infinite to handle infinite sessions keys.  Cron support re-worked to be based on actions.  Actions for performing cron jobs, updating profile fbml, updating fbml references.

Re-arranged a number of things to make it possible to connect to facebook API from non-canvas pages.  Added fb_actions, where actions will live that invoke facebook APIs.

Now using hook_fb to query add-on modules for facebook user id and infinite session key.  This allows us to display information about the facebook user on drupal's user page.  But more importantly lets third-party modules query for any information facebook provides.  And paves the way for interesting actions and cleaner cron implementation.

changed class name admin to admin_sidebar, because admin confliced with class used in node edit form
