core (menus): improvments:
- use the new convention for bridge names (getMenus ==> menusGet, etc.)
- menu now use canonical path, which is the untranslated path with each element stripped and lowercase, it must be unique by menu type
- added menuLaunch method to manually launch a menu like an action, canonical path is used instead of id
- added SECURITY_LIMIT_MAX constant
