- This is a half-step: the ViewStep shouldn't do job creation either,
eventually it needs to be the Config object, but this is better
than asking the widget (UI) to create some jobs.
- When updating login- or host-name, or the autologin setting,
set it in GS as well. This is a minor improvement over doing
it only when leaving the page.
- Since the Config object isn't complete, there are leftovers in
the widget, which has a fillGlobalStorage() for the not-jobs-related
bits previously in createJobs().
- make the HostName textbox just a view on the Config's HostName
- make the username and login textboxes view onto Config
- query the Config rather than the UI for job data
