'upgrader_process_complete' action for theme has 'plugin' type

[bamadesigner]

I believe the 'upgrader_process_complete' action for themes has the wrong 'type' parameter in the Theme_Upgrader class in the wp-admin/includes/class-wp-upgrader.php file starting on line 980:

do_action( 'upgrader_process_complete', $this, array(
   'action' => 'update',
   'type' => 'plugin',
   'bulk' => true,
   'themes' => $themes,
   ) );

should be

do_action( 'upgrader_process_complete', $this, array(
   'action' => 'update',
   'type' => 'theme',
   'bulk' => true,
   'themes' => $themes,
   ) );

Looks like a copy/paste error in [25806].

Pass correct 'type' parameter to 'upgrader_process_complete' action in Theme_Upgrader.
