function fb_custom_theme in Drupal for Facebook 7.3

Implements hook_custom_theme().

hook_custom_theme() is the new hook_init(). It is called before hook_init(), and therefore the first opportunity that a module has to act. Although this module is not interested in setting a custom theme, fb_canvas and fb_tab might, so we must initialize some data here.

This function is also called before node_access hooks. So the more we can initialize here, the better. That's why we initialize both $_fb_app and $_fb.

    // Initialize the PHP API.
