Loot update

There is a new node in the skill tree: increases the chance of chests spawning.

This is a way to find items and the the first test of consumables such as health potions!

So you now have an item slot next to your hotbar where you can store such things.

For now, the lil'adventurer automatically slides up to chests and loots them, but in the future I'm considering having it be a bit more involved somehow.
