BulletSim: move over and port the interface for BulletXNA.
...
Copied BulletSNPlugin.BulletSimAPI to a new
BulletSPlugin.BSAPIXNA.cs and then modifyed the latter to
comply with the BSAPITemplate definition. Not totally debugged
but the code is all there for an INI variable to select either
unmanaged C++ Bullet or the C# version of Bullet.

did the right thing for stopping (speed reducing to zero), it prevented
movement from starting (speed increasing from zero). Will revisit
when the generalize PID motor is debugged.

BulletSim: an 'if' to suppress multiple setting of avatar orientation.
...
Looks like the viewer bombards the server with avatar orientation
information (we're talking several hundred a second) when the avatar
is being turned or when walking. This change just reduces the number
of 'set' calls into unmanaged code.

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.

* Initial commit of BulletSimN (BulletSNPlugin). Purely C# implementation of BulletSim. This is designed to be /as close as possible/ to the BulletSim plugin while still being entirely in the managed space to make keeping it up to date easy as possible (no thinking work). This implementation is /slower/ then the c++ version just because it's fully managed, so it's not appropriate for huge sims, but it will run small ones OK. At the moment, it supports all known features of BulletSim. Think of it like.. POS but everything works. To use this plugin, set the physics plugin to BulletSimN.

BulletSim: add BSPhysObject code to manage registrations of preStep events. Use same to implement setForce and setTorque so the values are restored at the beginning of each step (since Bullet zeros forces applied last step). Simplify implementation of AddForce and AddTorque by relying on the addition of forces in Bullet.
