useful stuff for server admins: curl command now allows the host name to be

left out, like this:

http:///~nexuiz/files/
http://:8080/~nexuiz/files/

allows setting up the HTTP server for map downloads on the same machine as the
DP server on a dynamic IP without using dyndns.

Client needs to support this.
