Wrong Animation Used during CMO movement

[Russ Adams]

Here's another easy one to reproduce:

 1. Click angle <= 90 above the foot of the CMO. The CMO faces eastward. That's OK.
 2. Click angle >= 180 below the foot of the CMO. The CMO faces westward. That's OK.
 3. Click 180 >= angle <= 135 west of the foot of the CMO. The CMO faces westward. That's OK.
 4. Now, click 135 >= angle <= 90 west of the foot of the CMO.

The CMO faces eastward, this is not OK.

I believe that this is not a bug in angle math. Rather, the problem is that we don't have a north facing animation for the CMO. The correct behavior here is that the CMO should face northward when 135 >= angle <= 90. But, since there's no north facing CMO, the CMO is forced to face east.
