* Tweaks some locks when modifying an ODECharacter. This actually allows a user to log-in while the physics scene and the scripts are starting up. This also seems to smooth out the jerks on teleport/connect/disconnect a little bit.

* If you log-in while the simulator is starting up, you won't be able to move and the sim stats will say 0 FPS, and 0 Physics Frames and you may see only terrain.  Once the sim finishes starting up, it'll all resume as normal.
