Nix allow appending config + refactor

[toastal]

The motivation for refactor is wanting to still add my own values to the list such as

127.0.0.1 myproject.localhost

At present enabling will override existing configurations. This should fix that as well as other minor fixups along the way. Now with this config

{
   networking = {
      stevenBlockHosts = {
         enable = true;
         blockFakenews = true;
      };
      extraHosts = ''
         127.0.0.1 myproject.localhost
      '';
   };
}

And the lib.mkAfter will append the StevenBlack hosts list after my extra config.

127.0.0.1 localhost
::1 localhost

127.0.0.1 myproject.localhost

# Title: StevenBlack/hosts with the fakenews extension
#
# …rest of config

The docs were also updated to including following the user’s existing nixpkgs since this is probably what the user wants (not adding multiple copies of the expensive-to-download nixpkgs tarball).

Can review commit by commit.

Thank you for this @toastal.

I have a question. Why would someone ever combine a PR with a rant about "MS Github"? How is THAT, in any way, a good idea?

These are two categorically distinct concepts. It telegraphs a remarkable lack of focus. It calls into question everything else because it's so wantonly scrambled. Two separate concepts? two separate issues.

This repo, since 2016, has been mirrored to GitLab. https://gitlab.com/StevenBlack/hosts. There are other mirrors.

Closing. If you would like this PR merged, please resubmit without the bullshit.

I saw no mention of said mirror, but this is very good to know. I opened 3 cleaner merge request there as requested.
