GP-4740 Added undo/redo support to composite editor. Switched actions to use isEnabledForContext. Transitioned VT FilterFormattedTestField to GFormattedTextField and use for editor text entry fields. Cleanup of old datatype tree actions no longer in use. Lots of changes to improve handling of data type dependency changes and restored original DTM.
