'Panelizer' items not added to content types table

Note: I was a dunce and original posted comment/patch in the Omega queues issue for this.

In order to get it to work I had to move to the theme layer. Why? Not sure, but page_alter didn't have the content variables yet.

This is how I got it to work with existing code. I chose process over preprocess so that it runs last, hopefully avoiding anything running in preprocess and borking it p.

function panelizer_process_page(&$variables) {
  // Delegate.
  foreach (panelizer_get_plugins_with_hook('page_alter') as $handler) {
    $handler->hook_page_alter($variables['page']);
  }
}

I know page alter would be optimal, but I really do feel that this could solve problems across themes. It's probably a DrupalWTF. Attaching a patch so that people can at least patch Panelizer - or have this committed as a fix.

Forgot to mark needs review.
