Rewrite in Lua

[brandonsturgeon]

I love Moonscript for a lot of things. I could even argue that it's a good fit for this project.

However, I can't argue with the fact that most people can't stand it.

As this project expands and more people use it, I need to make sure people can feel comfortable contributing fixes and improvements.

To that end, I've decided to switch the project back to Lua.

This PR:

• Converts the whole project to Lua in a minimum working state
• Implements the changes from Add rudementary backup recovery and discord rate limiting #31 (resolving Needs to respect Discord ratelimits #30)
• Drops the logger requirement entirely, preferring a built-in option

If you want a language that compiles to lua that people would actually be able to stand, can always use typescript. At least that has benefits in strict typing, proper classes, etc, where moonscript is just completely different syntax only for a little bit of class syntax sugar.

The tooling for gmod isn't that great but it is mostly usable: https://github.com/lolleko/gmod-typescript / https://github.com/Vurv78/TSAddon
