Inventory Tweaks

1. Allow pills to stack, so that we can carry more than a few without having to scroll endlessly through our inventories to reach other items.

2. Allow us to drop shinobi headbands. I'm using the black shinobi headband, so I've got four extra headbands that I can't drop clogging up my inventory.

3. Split the inventory into several categories, either by adding actual extra tabs, or simply bolded dividers that would separate the items by type, like this:

==Consumables==

==Clothing==

etc.

Well, there's my 2 ryo.

I like everything but the last idea with the categories.

Same as Krypt.

make it so every time you rebirth and get genin again, it checks to see if you already have the headband.
