ctrlAltTab: misc improvements

Fix the "panel" icon to be symbolic. Make the overview parts only show
up when in the overview, and the non-overview parts (eg, the Desktop
window, if there is one) only show up when not in the overview. Sort
the different items consistently with their locations on the screen.
