Moves and looks

Moved many classes and deleted a couple because they were obsolete. Also
updated a few colours of text in in-game tooltips. Not too much. Oooh,
Almost forgot. Start of a sound engine. It's not done... far from it, in
fact. But I've made a start. AND... I keep forgetting things. A new
item. It's in the code as "witchsApple" however doesn't function as an
apple. It flings entities forwards. Still need to test it on other
entities but I don't want it to work on anything that's not living.
Actually, I don't want it to be used as a weapon either, thinking about
it. And the entities are messed up. Unfortunately.
