Remove 1.6.4 references from everything except
MinecraftObfuscationHelper.

1.6.4 compatibility is captured in its own branch.

Time will tell how much work (and if it will be necessary once mods
start going 1.7.2) to keep older versions alive.
Add better encapsulation. 
Call the correct method for pre/post render tick.
Change player movement to just using KeyBinding.setKeyBindState.
Remove MovementHandler extension.
Saves on lots of code maintenance and lets minecraft handle the logic.
Side effect is this fixes sneak speed and sprinting.
Also likely compatible with Mods that have their own movement handler
for unique character behavior.
Update to forge-1.7.2-10.12.0.1024 which updates deobfuscation.
Also fixed minor cosmetic issues.
Clean up a bit on joypad config menu
