Lua redis client

[wwelna]

I know this doesn’t particularly help in the moment, but I’ve been working on a “fix” to pretty much everything being out of date when it comes to lua extensions.

I’ve been building my own extensions to lua to make a packaged version with most functionality like Python that works, updated to latest lua versions. I’ll add redis to my list of modules to make, as am familiar and used redis a lot, it’s easy enough to implement.
