gui: show the loaded Sud's name in the window caption and forecast title

Window caption becomes "BrewPi - <name>" once a schedule is loaded
(back to plain "BrewPi" when empty/disconnected); the Automatic tab's
forecast title is now "<name> - N min total", replacing the generic
"Estimated course..." text while keeping the time estimate.
