Game cam and eye banking, control schemes

- ShapeBaseData has two new properties.  cameraCanBank indicates that the game object may bank its eye/camera, if supported by the object. mountedImagesBank indicates that mounted images should bank with the eye/camera in first person view.  Both default to false.
- Player supports 1st person eye and 3rd person camera banking when making use of the new ExtendedMove class.
- Camera class supports banking when making use of the new ExtendedMove class.

- GameConnection now has an idea of a control scheme.  This determines how game objects should respond to input events.  A control scheme may be set by either the server or client.  Current control schemes are:
-- Absolute rotation (likely though the ExtendedMove class)
-- Add relative yaw (from mouse or gamepad) to absolute rotation.
-- Add relative pitch (from mouse or gamepad) to absolute rotation.

- Player class supports the new control schemes when using the ExtendedMove class.
- Camera class supports the new control scheme when using the ExtendedMove class.
