Subject: Add lives

* Create life.vim to keep track of lives
* Players start with 3 lives
* Add increment and decrement functions for lives because they'll be
  useful in the future (although there's a more immediate need for the
  decrement function)
* Render lives at the bottom of the board
* Move the score line down so that it appears just below the life count
