Adding more DesignerSupport functions
The new functions/enablers are split into new classes. * DesignerSupportItems Helper functions to tweak and create items. * DesignerSupportProperties Helper functions to deal with properties and bindings. * DesignerSupportPropertyChanges Helper functions to deal with PropertyChanges. * DesignerSupportStates Helper functions to deal with States. * DesignerSupportMetaInfo Two helper functions to deal with meta info and notication. DesignerMetaObject is a specialized QQmlVMEMetaObject that implments notification of property changes and allows to create dynamic properties. DesignerCustomObjectData provides additional data for each Object. The main functionality atm is to keep the default values and bindings for properties, so they can be restored.
