Made it so you never have to leave the spacebar

One of my favorite parts about the iPhone app was that you could
navigate the entire app with one finger. Navigating through Clumsy bird
with space seems intuitive to me, and I had a hard time pressing enter
or left mouse clicking then automatically having to move to the space
bar in order to continue playing the game. Why bother even changing
buttons at all?
