Subject: BulletSim: Fix crash on the destruction of physical linksets. While
 fixing the above, add methods to physical body and shape pointer wrapper so
 routines won't have to know that IntPtr.Zero means no physical instance. Fix
 problem with physical linksets failing after a few sits and unsits by
 properly restoring child prom positions for compound linksets after multiple
 selection and deselections.

Subject: BulletSim: Add 'BulletSimData' which separates structures created for
 the operation of BulletSim and those defintiions/structures defined so they
 can be used in the unmanaged world. Consolidate setting of collision flags so
 implementation is not scattered.
