             - fixed "rotate manipulator"-button doesn't deactivate "transform joint"-button
             - "splitJoint" depends on "splitBone" in "skeletonEditingScritpting.cc"
             - it should not be possible to add/delete/split joints when not in reference pose
             - fix: joint inserted by "splitJoint" will not be deleted, when you click on "addJoint"-Button and then press on another Button
