Added BulletCharacterController.cpp & BulletCharacterController.h stubs.

Useage :
- Link action to key :
Input::LinkActionToKey(ACTION_TYPE Action, struct Key Button);
Input::UnlinkAction(ACTION_TYPE Action);
- Query action directly :
Input::GetStatus(ACTION_TYPE Action);
Input::WasPressed(ACTION_TYPE Action);
Input::WasReleased(ACTION_TYPE Action);

Also works with raw button, but not advised :
Input::GetStatus(Key Button);
Input::WasPressed(Key Button);
Input::WasReleased(Key Button);

Added RayCastResult & a naïve integration for EasyCharacterController.
Enjoy !

Small tweaks in the BtPhysTest demo.
Added Ghost Object skeleton (not tested)

+ weird racist test : the primitives only collide with their same type.

Phys::Simulation is now an entity.
Phys::Simulation now implements timesteps correctly.
