Allow URL parameter to load dashboard in readOnly mode when devMode is enabled
If the dashboard is loaded with the #readOnly
flat e.g. http://localhost:8080/#readOnly
it should set readOnly to true.
I would like to have some generic parsing of the #
-part of the url similar to URL parameters. #readOnly
would be the same as #readOnly=true
Changeing the reaonly mode in the UI should not change the URL (for now)
