New maintainer & Lua5.5 update for a package that's relevant for AeroSpace + sbar users ==> https://github.com/NixOS/nixpkgs/pull/498766

Could an existing maintainer take a look and merge? The maintainer that's on that package is non-responsive, and it's breaking a flow for people that did an update in the past 8 days.
This is a small, low-risk package update (0 Linux rebuilds, 1 Darwin rebuild), any nixpkgs committer can merge it.
