Updated to MC 1.7.10

Here's BeefCore updated to 1.7.10. It has been gradleized (gradlized?) for easier setup with IDEs, and for the potential to be shipped as its own thing at some point. If/when this is pulled, I will make the BR PR.
Considering it was called the "Server" tick handler, and that you only registered it on the server side in BR, I thought that's what you wanted. I'll remove it if you want.
