* Extended IReferenceLineReplaceHandler with DoPostReplacementUpdates to allow for actions to be resolved after the replacement of the ReferenceLine took place. ** Main reason behind this architectural choice, is allowing for UI updates from non-UI threads. ** ReferenceLineImporter makes use of this new method in the DoPostImportUpdates method. * ReferenceLineReplaceHandler now keeps track of deleted objects and closes views for those objects in the DoPostReplacementUpdates method. ** Introduced ClearResults class for this purpose. ** Updated DataSynchronisationService methods related to replacing the ReferenceLine and now keep track of both changed objects as well as removed objects. * Cleanup in some commands to use IViewCommands.
