Improved SceneInspector transform section.

The various transform components are now extracted out and displayed separately to the matrix as well. Fixes #896.

I've used the same superscript text as the "Inherited" label to highlight the source of the components, because it seemed kindof ugly to have it in full size text in the label. I don't feel particularly strongly about it either way though if someone else does. I did go with the Ben approved wording though so hopefully he'll be back at Image Engine before long...
