Very Simple Test Server/Client

run each in a separate cmd, the client will ask for IP address of the
machine running the server, so do that, and you'll get a java popup that
says "Hey, this was sent from the server"
Compiles but doesn't quite do anything yet

also fixed some indenting in Reversi.java to make a bit a little more
readable :)
will add more functionality tomorrow (Sunday), I think I have a fairly
good idea of what I'm doing here, which feels great
