EditorInspector - Custom EditorPlugin for Skeletons
Created by: marstaik
The current skeleton editor in the EditorInspector lags hard with many bones and is very inflexible and hard to use for editing very large skeletons.
This is an initial push for a custom SkeletonEditor that has an instant load for complex skeletons with a Bone tree, allows bone re-parenting, keying, enabling/disabled bone pose activity, and all the basics that the previous system allowed.
