//the networking operates seperatly from the main code. This is so we can have full control over all parts of the server sending prints.
//when we send status to the server, it replys with a print command. The text to print contains the serverinfo.
//Q2's print command is a compleate 'print', while qw is just a 'p', thus we can distinguish the two easily.
//save favorites and allow addition of new ones from game?
//add filters some time
//remove dead servers.
//master was polled a minute ago and server was not on list - server on multiple masters would be awkward.
