Subject: use libgit2 to track PRs (#10)

* nix: don't depend on registry for nixpkgs input

* use libgit2 to track PRs

* nix: don't use ci devShell as defaul

* crates: bump serenity from `9ad74d4` to `0.12.2

* nix: fix cross compiled builds

* crates: split more from client

* bot-jobs: update remote refs more efficiently

* git-tracker: account for HEAD commits

* bot-config: use nixpkgs branches from environment

* bot-commands: don't display branches prs haven't landed in

* git-tracker: return false when commits aren't found

this is annoying as a hard error since it turns out github will report
garbage merge commit SHAs for PRs that *haven't* been merged yet. yay

* bot: improve docs in some places

* bot-client: display invite link on start

* bot-http: add TeawieClientExt

* bot-commands: add /about

* docs: update readme todos

* nix: enable StateDirectory in module

* crates: bump to 0.2.0
