Monsters now drop any items that they're carrying upon death. Since crates are a type of monster they drop items too!
Currently they drop a crazy amount of items, as part of a loot & inventory test.
When dropping an item the surrounding 3x3 area is checked and the "most empty" tile is chosen. This helps to prevent too much item stacking. If there are too many items in the area they are stacked and upon stepping on a stack the player can pick which item from the stack to grab.
The inventory screen mostly works, it lets you organize items and drop them on the ground, can't equip anything yet though.
