Command docs vastly out of date

Atm one has to look at the code to see what the plugins do. Most of them don’t even have any docstrings.

At the time that document was created it was extremely difficult to keep up with the speed at which lazybot was being developed. New plugins were coming extremely fast, and changes were being made constantly to existing ones.

The original plan was to generate documentation and that's still what I'd like to do. The infrastructure is in place to do it. All commands can have associated docstrings. Even if they don't, they can and should. I don't know of plugins themselves can have docstrings, but that should be a possibility as well.

I'd love to do this, but I may not have the time for a while. This is a very important task for anyone who would like to take it on. I'll happily provide some support to anyone who wants to give it a shot. Otherwise, I'll get to it eventually.
