Handle ObjectSpin* packets to spin physical prims on Ctrl+Shift+Drag
Addresses Mantis #3381 The current implementation works as expected if the object has no rotation or only rotation around the Z axis; you can spin the object left or right (around the world Z axis). It works a little unexpectedly if the object has a non-Z-axis rotation; in this case the body is spun about its local Z axis, not the world Z-axis. (But SL also behaves oddly with a spin on an arbitrarily rotated object.)
