Provide a proper settings plugin instead of relying on a remote script

[rnett]

Applying a Gradle "plugin" via including a script (i.e. apply("some file") is frowned upon for a variety of reasons, including the lack of versioning, lack of dependency management (i.e. locking, or hosting in your own repository), and making build script compilation avoidance harder.

I don't see anything in your settings script that would be impossible to do via a settings plugin. For that matter, I don't see what value the settings plugin provides - it's easier and much better practice to just add the build plugin yourself.
