integrating tiwulfx more

started changing joptionpanes over to tiwulfx's messasge dialogs. much
faster response on them. moved the ConfigException from mainclient to
common. scan page now has colored background (same green as all others).
upon configuration error, system will ask to revert to local database.
will work on more specifics here later but intentions are create
database if needed, insert 'DEV' user etc.
