networking done for this build

[Hamilton Turner]

So i just committed, and I think that does it for the networking user
stories. There are some things I would like to talk about in class tho,
just fyi. Here is a list:

how to start up the networking with the game, so that clicking the
multiplayer panel is not slow
how to determine the initial name the player's host should be called
the getLocalHostURI function in the HostMonitor
whether or not the Host and the Client should be singleton's
using the InputPlayerDataPanel with networking stuffs
