Added hostname to the server configuration

This is in order to avoid default lookup for local address, which usually
caused the game to bind to a LAN address hence effectively disallowing any
other traffic in.

For now there is no option in GUI to configure the hostname. Menus definitions
are in the game files, so I should avoid any changes that can cause the binary
to be incompatible with currently available resource packs.
