Auto-Closing Inventory

Many people were annoyed that they couldn't just drag their mouse off of the inventory to shut it and continue with the game, so I rigged up some code to make that happen! Now the inventory closes with either the "close" button OR moving the cursor off of the inventory.

Inventory Colors!

I updated the inventory colors - slowly trying to find a cozier color scheme. I mostly wanted to get away from the "green everything" and make the chest a much more normal brown color.
