Add a warning dialog and a red dot for changes
The warning dialog appears when attempting to navigate to monitor and the red dot when a change is made to the workflow.
For now the dialog does not include the option to save from within it which seems reasonable.
Also when a change is made the red dot remains even if the user saves. An index needs to be added to the changes stack to follow saves along with the index of undo-redo.
