Expand fieldsets by default when creating new application.

Change the fb_cb url rewrite syntax.  Now use apikey instead of label.  This helps simplify fb_settings.inc.
multiple simplifications (fixes, lets hope) to fb_settings.inc.
fb_session.inc no longer needed (at least for time being).
more sanity checks and output in fb_devel.module

changed 'fb_session_no' to 'fb_session_handoff'
changed order of javascript event handling, hope to avoid bogus session change events.

numerous changes, especially to session management and url rewriting. performance improvements and code simplification.

Changes to fbConnect session management.  Changing session id when logged in via fb connect.  This prevents the Drupal session from conflicting with the fbconnect session, and ensures user is properly logged out when user logs out of facebook.

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.

Initial changes to use new session model (no "adding" of apps).
Still more work to be done version 2.x.

Numerous changes to Drupal for Facebook.  Significant updates.  Manual configuration changes required.  http://drupalforfacebook.org/node/1055
