Vetala Beta 0.4.4

[louisVottero]

• Added
• core.remove_non_existent(list_value) will return a list that has entries that don't exist in maya removed.
• core.set_tool_to_select() used before progress bar to hide some status line updates
• core.set_tool(context) added, used to programmatically set the current tool
• core.get_tool() returns the current tool
• core.delete_set(set_name) added. This a convenience to delete a set and all of the sets parented under it. Good for removing set_controls
• rigs_util.get_potential_top_control(top_group) looks at the controls and tries to find the control that moves all other controls.
  
  Fixes
• TransferWeight.transfer_joints_to_new_joints no longer works on joints that don't exist as well as some fixes
• Corrective mirror fix.
• rigs_util.Control.rotate_order(order) fixed
• rigs_util.get_potential_controls(top_group, namespace = None) fixes, top_group wasn't getting read properly
• rig_utils.MirrorControlKeyframes tested and some errors fixed.
  
  Improvements
• joint orient attributes inverse scale now works when there is one child. It will give warnings if there are grand children. Be careful when working with negative scale in a hierarchy.
• joint orient attributes XYZ inverse scale added. This will require you to run joint orient once on the joint to get the option updated.
• Workspace docking now works with Maya better
• Control tags only export on controls, this cleans up some control tag scene garbage that was happening
• follicle_to_mesh now uses rotate pivot to find closest face instead of translate. For most cases this should act the same. When follicle a cluster it should work better.
