Implement side-by-side tiling

Patch by Florian Müllner for Metacity
https://bugzilla.gnome.org/show_bug.cgi?id=607694

When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.

Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.
