Rewrote backend

[Stypid Mox]

Hey everyone, I thought I'd share this since I've been working on it for a while.

I've done a complete rewrite of the PHP backend of PhudBase-WebMud in Rust. This has a number of advantages, such as the product being a single, statically linked binary that can be easily installed, as well as efficiency (after playing on a MUD for a couple hours, systemd reports 100ms of CPU time used).

If you are interested, the project is located on GitHub.

Thanks!
