FEATURE: AppID/Secret can now be entered on the plugin's admin page. BUG: if a connected FB-App is deleted and a new FB-App is connected, the app_access_token of the former App remained in the config and made it impossible to activate Real-Time Updates with the new App. USABILITY: Now the user's connector settings page automatically recognizes if the connection is still valid and acts accordingly. SECURITY: XSRF-Protection.
