FauxGravity + Waypoint rotation and movement

Sorry no audio yet, I'll re-record again if needed. For now, here's an AI traversing a waypoint system along the surface of a sphere.

This is achieved by a projection of the Waypoint position to the Player's local X-Z plane so that the player will Look at the next waypoint (located at some angle across the sphere) as if it were on the same plane.

Thus relative Left / Right turning directions with respect to waypoint.
