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.
Manual Installation per https://nuskooler.github.io/enigma-bbs/installation/manual.html asks the user to use v18 whereas this script was defaulting to 14.
This caused me some frustration in getting my BBS up and running as I at first depended on the auto-install script.
For the less apt user, this might be a blocker to adopting this BBS Software.
