Peter Barker 676d75c391 Copter: correct namespacing of Copter modes
This makes us look like Rover and Plane in terms of namespacing for the
Mode classes, and removes a wart where we #include mode.h in the middle
of the Mode class.

This was done mechanically for the most part.

I've had to remove the convenience reference for ap as part of this.
