Outfit change demo

A gif showing equipping/removing gear with the inventory ui.

Inventory, and looting from containers and ... sleeping enemies are working now. The equipment screen, together with the color chooser located there, will come at a later time. 

Currently working on porting some stuff over from HR and constructing the dungeon from the "blueprint" shown in a previous update. That's pretty much all I want to do for demo II, and it should be here soon TM.
