Fixed the critical proxy issue from 1.4.0, allowing this version to run on servers without crashing.
Fixed grass blocks being burnable as a furnace fuel and being crafted into fuel pellets from 1.0.0
Found a solution to allow for one jar file to work across Minecraft versions as the code is the same. This means rather than having four seperate jars, 1.9.0, 1.9.4, 1.10.0, and 1.10.2 we can shrink that down to two: 1.9.x and 1.10.x
Removed unnecessary imports and comments from code as well as general code cleanup.
