This is a contingency for the event that the annotation feature is enabled but form saving is not. * A new field hasUnsavedChanges is added to the save result, this is set when there are edits but form saving is not enabled. * When this field is true, a dialog is shown to the user allowing a choice whether to continue to enter annotation mode or not. * The annotation toggle event is made custom to avoid re-entrancy when entering anntation mode is aborted.
