Subject: BulletSim: tweeking avatar capsule code in an attempt to have
 asymmetrical avatar capsule work now that rotation is being passed from the
 simulator. Turns out the Bullet capsule is just not very functional: it
 doesn't scale properly, the implementation only half does asymmetry and, in
 general, is hard to work with. Avatar shape is about what it was before these
 changes. Added initial data structures for avatar shape mesh.
