Bosses and Touchscreen support...

Well, there's finally something that looks like a boss fight. It's pretty rough yet, but when polished I think it would fit well in the game.

Touchscreen (at least on my android phone) seems to work fine.

On the first builds I made some onscreen stick and buttons, but I was spending more time (while playing) looking where to put the fingers than actually seeing where the enemies spawn. So I decided to remove these on-screen controls and do something nicer.

Basically, the screen now is split in two. The ship fires when tapping on the right half, and swiping left and right changes to previous and next color. Swiping (and dragging) left and right on the left half of the screens rotates the ship, and doing the same up or down makes the quick 180º turn. I think these controls are much better, as you don't need to use the exact finger positioning to do some stuff.

Oh, also added some stage alerts to make it a bit less boring.
