nvim: Updates

* Drop ~p00f/ colorschemes; the added treesitter queries seem to be
  breaking despite them not being activated at all, which is annoying
* Disable max_lines warning in diffs.nvim
* Effectively disable mini-completion auto-completion. May end up just
  backing it out altogether. The completion running all the time causes
  a lot of lag.
* Add support for buf-config filetype for buf config files.
