BulletSim: fix odd code that wasn't really recomputing the mass of a
...
rebuilt linkset. I was burnt by making get/set methods with side
effects. I should know better.

BulletSim: scale the force for external AddForce by the simulation

step time so it will be applied completely the next step. The internal
AddForce routine does not scale the force.

object's individual gravity to the world gravity when the object
is added to the physical world.

BulletSim: Rename some of the interface structures (BulletWorld, ...)
...
to get ready for...
Start creation of BulletAPITemplate. This defines the abstract interface
functions. Following commits will move over to the new interface.
This will enable switching between the managed and unmanaged version of
Bullet.

BulletSim: Default avatar density changed to 3.5 which is WAY closer
...
to the SL value.
Fixed frictin values for physical materials which were just wrong
which caused things that should have slipped to not.

BulletSim: Fix single physical prim reporting its mass as zero.
...
Properly return root mass as mass of just the root prim rather
than the mass of the linkset. SOG has the logic to add the masses
together to get the linkset mass.
Update TODO list.

* 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: remove post step one-time taints (doesn't make any sense). Rename pre and post step event invocation routines to Trigger* to be consistant. Remove old, unused code.

BulletSim: Fix llApplyImpulse so it works after the first impulse. The problem was Bullet deactivating the object between the pushes (when, as far as the physics engine is concerned, it isn't moving).

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.

BulletSim: Move all the parameter variables, tables and get and fetch logic to a separate, static class for easier addition and to remove all that bulk from the BSScene class.

BulletSim: small fix to avatar movement motor use which keeps avatar from flying up forever. This doesn't fix the overall problem but keeps avatar flying from being totally unusable.

BulletSim: avatar movement smoothed with motor that modifies avatar velocity to target velocity. Fails in incorporating physical world effects (gravity) so avatar doesn't fly correctly.

BulletSim: Check for unspecified TimeScale in BSVMotor and don't scale if not specified. Add test dump routine. Don'e zero current and target values when error goes to zero as the values could be used externally to store the actual target values, etc.

BulletSim: angularMotorUp working again (seems a little slow as it takes longer than timescale to correct, but getting better). Disabled angularDeflection (need to resolve interactions between angular corrections). Update TODO list.

BulletSim: apply friction to linear and angular motion before returning advanced motor value. This seems to be the problem with BulletSim vehicles turning too quickly. Also removed the configuration parameter that controlled the timestep scaling kludge for angular velocity that was added to research the question of quick turning.

BulletSim: fix vehicles going underground when unsat. Problem was that, when doing unsit, the order of operations on the prims and the vehicle is very chaotic and not in a good order so the root prim was being left physical and thus it fell for a bit. Also changed default of velocity scaling to be closer to the movement standard.

BulletSim: add parameter to UpdateProperties call into the linkset so changes from the physics engine can be differentiated from changes made by the user. This eliminates a linkset rebuild loop. Also add logic to not rebuild or freak out when the object/linkset crosses a terrain boundry.

Return the last set targetVelocity rather than the current velocity as the default action made available in PhysicsActor.TargetVelocity. Doesn't change any physics operation but makes DSG work better as the targetVelocity value does not keep moving around.
