Fix bug 5333962 - Problems with no action bar/overlay action mode

Change the standalone action mode window for overlay mode to be of
TYPE_APPLICATION. (This also fixes a bug where overflow menus would
not work properly on these types of action mode bars.)

Set exitFadeDuration on btn_cab_done_holo_* drawables.

Remove no-window-focus override selector states for selectable item
backgrounds to allow proper touch feedback on windows that do not have
focus but that the user can interact with.
