Cloner and Ellispse
StyleProperties are StyleTags now
New CompositeProperty which consists out of a number of any other Propeties.
PropertyTransform is now TransformProperty and Composite of RealProperties
Fixed small bug in RealProperty (update is invoked on editingFinished but valueChanged)
Properties owner is set in Constructor. Fixed bug so cloner can be saved
Tags can have Properties. Much easier to create new tags.
