Somewhat improve avatar region crossings by properly preserving velocity when avatar enters the new region.

Browse Source 
This commit addresses the following issues were causing velocity to be set to 0 on the new region, disrupting flight in particular
* Full avatar updates contained no velocity information, which does appear to have some effect in testing.
* BulletSim was always setting the velocity to 0 for the new BSCharacter.  Now, physics engines take a velocity parameter when setting up characters so we can avoid this.
This patch applies to both Bullet and ODE.
