Push #3

Changed some things up. Added in the alphabet screen. I think I might
just not have an options menu.. or music... I don't like music on these
types of things. So... No need for an options menu just to adjust the
sfx level. But, good news, this is now fully usable. At least, if all
you want to do is "play a Greek letter game"... Now to figure out what I
should add to it next...
