Release Name: rfacebook

Notes: - split up the Gem (core library) and plugin (Rails extensions) - you will now have to update your Rails plugin separately from the Gem - better documentation in the core library - deprecated all the confusing is_valid/is_ready/is_activated/is_expired methods in favor of simply 'ready?' and 'expired?' - removed the plugin code from the gem...the Rails plugin is now much better-separated - moved unit tests that applied to the core into the Gem itself (rather than the plugin) - cleaned out some unnecessary code in controller_extensions - refactored signature checking so that it happens in the plugin rather than in the core lib - added ssh_port to tunnel configuration (if for some reason you dont use 22) - added 'log_out_of_facebook' method to force a user to log out (clears the fbsession data)
