Fixed scaling issue with skeleton, can now scale the root object and it should affect the scale accordingly.  Added the ability to Flip the skeleton on the X or Y axis, as well as to do so per bone when not in edit mode.  Fixed z-sorting when the character is using the shadows shader, also should work when flipping bones.  Added a tool for editing sorting layers for an renderers and their children, can add an int to the sort layer, create Materials from Renderers, can also copy sorting layers, positions, and rotations between objects that have identical names.  Merged ResetSortingLayerOrder functionality into SortLayerMaterialEditor.
