These packages are obsoleted by the promises API to the built-in Node fs
module. The fs-extra package is also causing problems with broken APIs
that don't behave the same as Node's fs module, and throwing errors
without code properties on them.
The FactorioServer.checkForUpdates function would wrongfully assume that
the version running would always be listed on Wube's archive page, and
throw an error if this was not the case. Ignore version checking logic
if no suitable latest version could be found.
