Removed the render engine. It's probably better to learn to make one
ourselves anyway. We can make it into a library later.
Removed duplicate LWJGL jars, we're using maven for them anyway.
Changed our JSON parsing library from "json-simple" to Argo (Minecraft's
own library)
It's looking like we might be able to use mostly the same code from
Minecraft due to all of these open-source libraries being used.
