Welcome screen: open module once the open in vesselview is clicked
SQUASH WITH WELCOME SCREEN Second pass
Welcome screen: add return to welcome button
Welcome screen: Developer mode hack

-d or --developer will start vesselview without the welcome module, thereby
getting rid of the welcome layout and user offuscation.
It's hackish however since it gets rid of some settings and artificially
remove the Welcome module from the loaded modules.
It's also not listed in the help module.
