Enable hot corner for triggering the overview mode

Browse Source 
Use the 1x1 actor in the top left corner of the screen to enter and leave
the overview mode by just moving the mouse over to it.

No delay is used for triggering the hot corner because a delay significant
enough to allow moving away the mouse to avoid triggering it ruins the desired
flow when triggering the hot corner is actually intended.

The hot corner is not enabled in the full screen mode because the application
or the virtual system might have a hot corner of its own in that place.
