========================
= Hide App = <- menu_mac_hide_app
= Hide Others = <- menu_mac_hide_others
= Show All = <- menu_mac_show_all
========================
= Quit = <- menu_FileQuitItem
========================
If any of them are ommitted from the application's DOM, we just don't add
them. We always add a "Quit" item, but if an app developer does not provide a
DOM node with the right ID for the Quit item, we add it in English. App
developers need only add each node with a label and a key equivalent (if they
want one). Other attributes are optional. Like so:
<menuitem id="menu_preferences"
label="&preferencesCmdMac.label;"
key="open_prefs_key"/>
We need to use this system for localization purposes, until we have a better way
to define the Application menu to be used on Mac OS X.
