Let's talk about rain

[NiLSPACE]

I created a plugin once that pretty much implements a little more advanced weather command: https://github.com/NiLSPACE/WorldUtilities

With that you you can turn off the weather changes completely. I'm afraid you can't make rain periods longer or shorter with it. I haven't used the plugin in a while, so it might not even work anymore. And I don't like the code, but whatever
