[Simian]

* Created an LLUDP folder to hold extensions that are purely LLUDP packet handlers. This is not a complete abstraction away from transport protocols, but it's a start
* Moved physics code from Movement.cs into PhysicsSimple.cs, and moved the physics loop into a thread in SceneManager
* Simian.ini cleanup
