function fb_connect_app_init in Drupal for Facebook 6.2

Same name and namespace in other branches

1. 5.2 fb_connect.module \fb_connect_app_init()
2. 6.3 fb_connect.module \fb_connect_app_init()
3. 7.3 fb_connect.module \fb_connect_app_init()

Prepare for fbConnect use. Because a single Drupal might support multiple apps, we don't know in advance which is the fbConnect app. Theoretically, it might be possible to simultaneously use multiple apps and fbConnect, but my suspicion is facebook would throw a total hissy-fit if you tried.
