== Action Editor - Action Groups finishing touches ==

* Added a new tool "Synchronise with Armature" (found under Channels->Grouping), which synchronises the grouping of action-channels and the grouping of their relevant bones. 

This only works when the active object is an armature, and the action isn't pinned. All of the action's action-channels are removed from their groups, and are added back into groups according to the current grouping of their corresponding bones. 

A bit of testing for weird cases is needed.


* Group colours are now not drawn if the group originally was using the 'default' colour-set.
