Add a 'More' control to the applications display in the overlay

Browse Source 
mode. When this control is clicked, documents display section slides down,
workspaces display slides to the side, and a multi-column applications view is
presented to the user. "More' control is replaced with a 'Less' control. When
the 'Less' control is clicked a default overlay view is restored.

Clean up positioning of the components of the overlay sideshow
and the items within generic item displays.
