Subject: [PATCH] Enable grab feature (Ctrl+Drag) for non-physical link-sets
 and add code to handle spin (Ctrl+Shift+Drag)

This patch fixes permission issues with dragging scripted objects. As on LL grid, scripted prims can not be dragged now. Also after dragging, the group was not marked as updated. This meant that after the region was restarted the group would revert to its original position.
