Add method to close socket. NOTE: This change BREAKS THINGS and the demo NO LONGER FUNCTIONS. The problem is however unrelated to the commit--this code simply reveals an already existing bug due to the socket number being uninitialised. Now I've found out why the problem occurs I can fix it in the next commit.
