Subject: BulletSim: Update BSCharacter to use API2 interface. Add capsule
 shape to BSShapeCollection(). Remember last updated values so inter frame
 diffs can be computed. Parameterize avatarStandingFriction and reduce to 10
 from 999.     The latter high value made avatars very hard to push. Set CCD
 parameters for prims and characters of specified.
