Add a menu display to applications

Browse Source 
ShellAppMonitor now depends on gmenu to load menus.

Use the menu data from ShellAppMonitor to show a menu list.

GenericDisplay implementations can now have a sidebar area.  We
handle keystrokes such as left/right explicitly.

Some internal API changes to account for the fact that a display
can have another filter in addition to the search.
