Features:
Re-added clicking outside of inventory to drop items
Fixes:
Dupe glitch by itemizing a negative amount
Heart decreases not decreasing visually on client if your health was higher than the new amount
Shield and eating not functioning properly on hands after going to the nether
Itemizing > 16 organs would put it all in one stack
This is the first build I've deemed production ready (it's taken 7 previous versions of bad code and crashes to get to this point).
The README has more specific information on usage, but I hope I've documented everything properly up to this point.
Feel free to file an issue if it crashes or otherwise does not meet documentation.
