* implemented MoveTransformersCommand (so Transformers can be

drag sorted now)
* implemented RemoveTransformersCommand
* implemented StyleListView (I promise, this is the last list view :-)
* implemented adding new styles via the Style menu
* implemented selecting the Style of the currently selected Shape
