DemonwareOverride: allows using new online services replacement

Right now the replacement server allows creating/joining/searching lobbies
There's no support for the rankings or ghost uploads right now, but hopefully will be added in future

To use the online just go to multiplayer menu, choose online, then register a new account
Your username/password will be stored in hashed form on the server

To host games you may need to forward ports 41455 / 41456 / 41457 in your router, until we add a UPnP solution for the game
