Bugs fixed:

• In dumps, indicate non-responsive rigid bodies.
• In visualizations, draw non-contact physics characters in yellow wireframe.

Other important changes:

• Turned off hardware skinning in DacLinks.createSpatialData() to provide access to the true positions of mesh vertices.
• Modified the DynamicAnimControl.centerOfMass() method to also estimate the velocity vector of the center of mass.
• Links in kinematic mode now update their body's location and velocity for every frame, instead of just for each timestep.

• Renamed DacPhysicsLinks to DacLinks. (API change)
• PhysicsSpace accessors now return physics-object collections sorted by ID.
