HEAD
- rename: Insert Menu -> Templates
- translation of the menu title removed from create_submenu in order to allow more than just (translateable) strings for the menu title (e.g. custom html including images).
The calling function is now responsible for translation of the menu title.
All existing calls to create_submenu have been adjusted.
- moved special treatment of the Personal menu from create_submenu to primary_menu
- added help icon to Help submenu in XML editor.
