(c2e1b24e2) Fixed remote characters sliding slowly to the left in multiplayer. Happened because linear velocity was written with an accuracy of 12 bits, causing the lowest possible value to be about 1.5 cm/s. Now extremely low velocity values are rounded down to zero. The server also now quantizes the LinearVelocity/AngularVelocity values, which should make position syncing a little more reliable because the server runs the physics using the same rounded values as the clients.
