interactive: allow snapping to corner edges

Browse source 
In addition to <snapping><range>, <snapping><cornerRange> configures the
distance from the screen corner to trigger quater window snapping.

Also, new values "up-left", "up-right", "down-left" and "down-right" are
allowed for <action name="(Toggle)SnapToEdge" direction="[value]"> and
<query tiled="[value]">.
