Title: Replaces object verbs Rotate, Flip, etc with MouseDrop()

Drag towards cardinal direction = set object to that direction.
Drag again towards the current direction = flips object (if applicable).

Affected objs: Doppler arrays, pipes, disposals pipes, transit tubes, chairs, windows, windoor assemblies, emitters, PA parts, infrared assemblies.

This kills 18 object verbs.
