BulletSim: reclass BSPrim into layers so linkset and physical world displacement is implemented as overlay classes rather than if statements scattered about.
BulletSim: include the linkage to the layered prim implementation. Separate layers for physical (vs simulator) location displacement and linksets.
BulletSim: add initial instance of the ExtendedPhysics region module which adds new LSL commands for extended physics functions. Uses the modInvoke system. Disabled by default.
BulletSim: fix avatar bobbing or jiggling while stationary flying.
Various comments and debugging message mods.
BulletSim: Change BSCharacter to use new base Density and Friction
variables rather than own local varaibles.
BulletSim: add parameter to set global contact breaking threshold. Update DLLs and SOs for setting same.
