Item drops and item use

I've been lacking on updates since I had to pack up last week, then move house over the weekend. I'm now all set up again.

In the background, I have still been banging out TODO items. Some updates:

- fixed some bugs with sloppy menu navigation
- added enemy item drops  (there's a 75% chance the skeleton will drop some health)
- added item use mechanics (using health items will restore health)
- added some sound effects (they are a little on the loud side, going to adjust that and add general volume controls)

The backend mechanics for item use are fully in place, so I can execute any function I create based on an item's properties. I will have jump height, speed, attack modifiers and the like, in addition to equipment that will provide more persistent effects.

Most of the menu remains 9999999 fake stats, so I still have to work on that, but I'm probably going to do equipment first. Now that I am getting closer to an actual alpha state, I need to make the "quick" part of the "Quick Level Up", so I think the first wearable is going to be some boots or gloves that provide continuous EXP gain. I'm eager to get some incrementalism goodness going.

I should be back to updating 1-2 times per week, now that I'm moved. Stay tuned!
