Convert singleplayer game to multiplayer server

[nielsmh]

It'd be neat to have a feature to convert a singleplayer game to a multiplayer server, without going through a manual save-quit-reload cycle.

I have seen some games where single-player is just a multiplayer server that only accepts one local connection.

@M3Henry That wouldn't be appropriate here as it would involve running the whole simulation twice.

For the record, the background for this idea was some discussion on IRC about maybe adding some kind of IPC interface to OpenTTD that would allow other local software such as Discord or perhaps Steam to query status of the game, and help with matchmaking with friends. The idea here being that if you were playing singleplayer you could simply invite your friends to the game and it would be converted to a network server.
