Frame: new behavior for revealing/hiding the Frame with the mouse

After discussing with Gary I prepared this patch to change the
interaction with the Frame in the following manner:

- you can reveal the Frame by going with the cursor in one of the
  hot corners

- you can hide the Frame by going with the cursor in one of the
  hot corners (and the Frame is visible)

- the Frame is not hidden on mouse out (leaving the Frame)

- (as before) you can hide/reveal the Frame with the designated keys

- the Frame is hidden when you switch between activities
  (todo: hide as well when resume in the Palette is clicked)

- the Frame is hidden when a zoom level is selected

- (as before) you can use 'alt-tab' to cycle through the
  running activities

- drag & drop is currently not working, SL #3811
