Update function.php

I propose a union with new_peers_list so that there are more peers polled for the hash.  Servers with low active peer counts (4 - 6) a few bad peers could disrupt the generating peers list.  In addition, the server itself could be poisoned and help propagate the bad data.  Polling more servers will help flush out the bad servers
