Log:
* Move the nominal center of mass toward the back of the aircraft.
The new position corresponds to the nominal center of lift at
subsonic speeds, which can be thought of as the reference cg
offset.  CM(alpha) incorporates the negative static margin features
at this cg position, and additional shifts (due to loadout and fuel)
will increase or decrease the static margin.

  * Refactor rotation animation classes, moving some common operations
    to the base class.  Add an optional non-linear gain to the rotation
