Why?

GitHub Resourcepack Manager is a mod meant only for servers, this isn't in any way useful for singleplayer or opening to LAN!

I saw in one of XisumaVoid's videos (this one, to be specific) that they have something set up on HermitCraft which allows them to update their resource pack through GitHub.
I tried searching for it on the internet, but couldn't find it, which is why I created this.

How?

The mod hooks into the Minecraft server (which uses netty) and hosts an HTTP server on the same port and ip (included library for it here).
Said server will listen to POST (webhook) requests sent by GitHub to update and GET requests sent by a client to download the pack.

After the mod is notified of a push to the repository, it uses the jGit library to download a copy of the repository.

Once a copy of the repo is acquired, it will try to find a pack.mcmeta file or packs folder inside the (configurable) resource pack directory, pack it all up as a .zip file and host it.

After that, it modifies the server.properties file with the correct sha1 hash and download url, while randomizing the zip file name, otherwise the client thinks it has already downloaded it.

Finally, a notification is sent in chat that there is a newer version of the pack available, which they can get by rejoining the server, or by clicking the button in chat, which doesn't require leaving the server. (I guess manually running the /gh-rp-manager request-pack command should also work.)
