Loot sparklies!

Had to break down and add some sparklies to loot chests. I was losing them in the darkness, and without a mini-map system in yet (that reminds me; TODO: Add minimap) it's easy to forget a loot chest or two. The sparklies don't cast light, they just use additive blue particles to mark a location in the darkness.

I added Build and Spells action buttons to the quickbar. Combat skills go in one, buildings in the other. Buildings include all of your workbench equipment, as well as other things yet to be added such as barricades and even siege machinery. I also finally added a custom cursor.

Just small stuff today.
