Consistent Cubemapping

See https://github.com/Azaezel/Torque3D/commits/tsstatic_DynamicCubemaps for separated out steps based on dev-head at time of writing.

Adds shapebase reflection functionality to tsstatics, corrects dynamic cubemaps using instancing which causes very nasty artifacting, defines a baseline DefaultCubeDesc for reflector datablocks, adds it to the mossyrock (boulder),
 and finally places an example in emptry room of a tsstatic refferencing the reflectordesc.
