[crossfire] new metaserver

[Anton Oussik]

It's great that so much attention is being drawn towards making the
server list accessible. However, will it then not be easier to just
DoS attack the actual CF server? How resiliant is CF server to DoS
attacks? There already exist several methods that make the server
crawl even on fast hardware, such as loading huge maps and casting
several meteor storms. After providing a reliable way of clients to
connect to the server, the next step would be to make the server
itself be more reliable.
