1.7 Fixes!!

Holy moly, Michiyo you will love what my friend was able to pull off. ALL the bugs were fixed. This fixes the GUI issues, the crafting issues (yes! You craft with 4x64 paper! No intermediate steps required!), the block hardness issue, and the container issues!
Most of the commits below is me cleaning up my old solutions, and manually merging commits. Sadly, you'll have to do a manual merge yourself.
