Bugfix:

* Bone Paths calculation should now work on unsaved files. This long standing bug has been hacked around by manually forcing OB_RECALC to be set for the active object (depsgraph should really do this, but it doesn't!)

* Added waitcursor for calculating paths (useful on longer paths). I was going to add a progressbar as well, but that decreased performance overall.
