add it to luarocks.org

I was going through the list of lua packages to update in NixOS/nixpkgs#33903 and this one seems simple enough that I can convert it automatically from luarocks to a nix derivation. so adding it to luarocks could be nice.

Can awesomeWM find packages installed with luarocks? What environment variables does luarocks, that are usable by awesome to pick libraries up?

Can awesomeWM find packages installed with luarocks?

Commit 202be62157103c34fab12283fe8d6e46df615b67 changed the default config of awesome so that it should be able to find packages installed through LuaRocks. This commit added pcall(require, "luarocks.loader") to the beginning of the default config. Assuming awesome can find luarocks, this should make packages installed through luarocks available.
