Version 1.4, Pre-Release 6

Inventory update! Added a hotbar, and removed item stacks. You'll notice that the hotbar still displays an item count, and it may seem a little odd. It's supposed to show how many total items you have, if any of that item is in the inventory, but I was having a lot of trouble deciding what to do if there were multiple in the hotbar at the same time. I decided to just have them both display the total, including themselves. Please, give me feedback on how to improve this system, and the item selection system.
