* Changed update callbacks for several armature properties to do proper depsgraph flushing instead of sending redraw notifiers
* Wrapped preview-range settings for Scene
* Fixed bug with 'parent-type' enum menu for Object parent-type. The problem here was that PARSKEL was used and is still used for both Armatures and Lattices, but the lattice entry would always override armatures entry. Now, when dynamically building the list to display, the function to add these is given the specific item to use, and has been made to stop after the first match has been added. Hopefully this doesn't break anything else...
