Bug 573078 – Add better transitions when expanding the item displays

Browse Source 
Add black backgrounds to each item display, as well as a black
background with a full-screen height to the workspaces display.

Update the expanded item display up front when 'More...' is clicked, and
reveal the additional items gradually when the other components of the overlay
slide away.

Raise the documents display up gradually as the applications display above it slides away.

Reverse the process when 'Less...' is clicked. First, gradually cover up additional items by other components, and then update the displays to contain fewer items.
