Implement rudamentary monitor snapping after move.

After a monitor has been moved, snap it to the closest monitor.

NB: This should fix cases where a monitor could not be positioned next
to another monitor which had a resolution of 1368. Previously, the
second monitor could only move to 1366 due to a rounding issue when
converting coordinates to virtual. Now, the second monitor (when
finished moving) will Snap to the proper position.

NB: (Currently) In order for the snapping to work, either the
monitors' X axis or Y axis must be equal. Ideally, this should be
fixed to allow for some percentage of position flexibility.
