Yay Javascript

Three major updates:
1) Both the master and the remote clients use the same page/code.  Now
the remote players don't have to go to player2.html. You just select
which one your are.
2) The main player can now select a name/color!  Woooo
3) Now, when someone closes their tab, it automatically deletes them
from the game world!  It even ends their turn if they quit on it.
