Added basic start state
Removed all the keys we're not using
Added a basic start screen
Slight modification to duck speed and bg image to give more play room
Made start screen font more awesome
Made a more pixelated duck
Added tilting to the duck when he(she?) flaps
Tweeked speed and bouyancy for what seems like more fun. We'll see when we get obstacles
Using new duck
Mostly collision detection stuff

Also made sure FloatyElements only allow one instance per ID (facilitates
easy resetting of elements, plus obyes HTML validation)
Added basic obstacles

Also made .elem a recursive part of FloatyElement, but that's not being
used yet. Part of this was changing how init functions happen to put a
post_init hook into FloatyElement.
