Vetala Beta 0.5.1

[louisVottero]

• process.import_data now works with slashes, eg. process.import_data('wip/structure')
• Deadline batch submission is working better
  
  Added
• Cone curve shape
• In Maya Ascii and Maya Binary data ui, a remove references button has been added for convenience.
• class deform.ClusterCurve now has the option to also cluster a second curve at the same time, this is currently being used for bezier surfaces
• class rigs.FkCurveRig now has a bezier option, still mostly experimental, but has been tested
• class rigs.TwistRig has some fixes. It allows for inst.set_rounded for when the setup is working on its own rather than part of an arm or leg.
  
  Fixes
• geo.create_oriented_joints_on_curve, description wasn't being passed in properly, numbering was sometimes out of order.
• class deform.SkinJointSurface, this class is like ClusterSurface but uses joints. Fixed the joints being placed on both ends when doing inst.set_first_joint_pivot_at_start and inst.set_last_joint_pivot_at_end
• process.set_data_override now properly handles put data. So that put data in scripts run remotely exists in the current process.
• class rigs.SparseRig.set_scalable has been reverted to work the same as in older vetala with an option to make it like the new one using keep_negative_scale flag
• class deform.TransferWeight now has a fix for inst.transfer_joint_to_joint to make it more accurate
• minor code completion fixes
• fixes to export deformer weights - tested double deltaMush and a cluster on one mesh and exports/imports properly.
• fix to mirrored corrective name building so it handles side in the name more gracefully.
• class rigs.IkBackLegRig fix for inst.set_duplicate_chain_replace
• minor fix for rigs in rigs module when no joints passed.
• fix to core.delete_outliner_sets, properly removes nested sets
