* Log progress messages when loading OAR files with a lot of assets

* Change the PhysicsCollision callback for objects to send full contact point information. This will be used to calculate the collision plane for avatars
* Send the physics engine velocity in terse updates, not the current force being applied to the avatar. This should fix several issues including crouching through the floor and walking through walls
