NMS-Compatible Alpha Release

I am running Thermos and I wanted to get NBT tags of item through a plugin. Well, lots of new plugins are cross-version compatible and use java reflection to get NMS classes which Thermos' mappings can't handle. That's the reason for NMS classes to be included in Thermos.

Just replace old jar with the new one

THIS IS ALPHA and not yet tested, use at your own risk!

Libraries are the same, if you have previous version, you don't need to download them again!
