Update bbs.js to for Config Init Enhancements

If a new user of enigma-bbs tries to run ./main.js it will now explain why it can't start and suggest running './oputil.js config new'

In addition, in the event of an error scenario it will exit with exitcode 1 so that systemd / other tools that bring up the service will be able to detect than an error had occurred -- process.exit() defaults to 0, and therefore would not have been caught.
