 Here's a really simple patch, that fixes the little bug seen
 [http://developer.pidgin.im/attachment/ticket/2510/away.PNG here] in
 #2510. As far as I can tell, `new_menu_item_with_status_icon` is only used
 to add statuses, and they never actually use a mnemonic. This patch just
 switches the menu item to a label without a mnemonic. This should be
 consistent with the dropdown in the Buddy List.
