Version 3 - Even simpler usage, new API endpoint, SSL support

Since version 2, a new API endpoint has been set up on Itch.io, I've added the capability for secure connections if libcurl is available and luajit-request is included/installed alongside your project/game. I've also changed usage so that it works like a standard module instead of requiring you to use threads and channels, but it is backwards-compatible with the old usage as well.
