Also a new method to publish feeds via showFeedDialog.  This currently requires fbconnect.  Later can be made to work with canvas pages, too.

#360334 (work in progress) use getAppProperties to learn the canvas url, rather than forcing the user to type it.

very little testing, may be buggy

Now using latest PHP libs from facebook.
Replaced users_isAppAdded with users_isAppUser

avoid escaping markup too many times.  Allows feed links to display properly when HTML excapes are included.

Support for custom triggers, because Drupal's trigger mechanism is hard for third-party modules to customize.

Infinite session no longer required to register a feed template.

Potential security issue here, so enabled only when fb_session_cookieless_iframe variable is set.
Solves a multitude of session state issues, particularly on iframes in safari and ie6 where cookie support is less than acceptable.

Added a block and callback which help keep canvas page session in sync with other requests (iframes, etc).
Added fb_canvas_form_action_via_facebook, to suppress the default form alters.
Fixed indentation.

Still TODO: clean up all references to FB_FBU_INFINITE_SESSION

Changed user handling.
Both of these changes are designed to make fbConnect authentication easier to support.

Fixed indentation of source code.

Fix invite links
