[PATCH] Support for toggling Menubar visibility on spicy

[Silvio Rhatto <rhatto@xxxxxxxxxx>]

This patch adds a submenu item at the Views menu
item which allows to hide and show the Menubar.

The functionality is also available using Shift+F6
keyboard combination.

This feature makes possible a more seamless
integration between spice guests and the host's
window manager.
