Update non-web related dependencies to their latest version were
possible. It appears yargs has changed its parsing of command line
options to no longer remove a layer of quotes.
The LTS releases for v12 and v14 are already end of life and the v16 is
end of life in under two months from now on. Bump supported version up
to v18 as it does not make sense to continue to support EOL releases.
Even if we wanted to keep supporting them, our dependencies will not.
Note that Node.js v18 is currently not avaliable via the NodeSource PPA
on Ubuntu 19.10 and below or Debian 9 and below.
Fix the installer wiping the package.json file due to a call to
outputFile that needed to target the original file being incorrectly
changed to safeOutputFile.
Provide a create package for the clusterio npm org which gathers the
necessary details to install a working cluster either as standalone or
as separate nodes.
