Subject: [PATCH 15/44]     Changes to global menu applet

Some changes made to global menu applet:
    1. Use "application-menu" icon in compact view.
    2. Show a warning sign when global menu style is not set to "Widget".
    3. When in a vertical panel force use compact view.
    4. And some minor changes and cleanup.
