Remove network connection from local games

Browse Source 
This removes need for TCP network connection in single-player games.

Instead, game will now create internal pseudo-connection that performs
client<->server communication by posting sent messages to client/server
asio::io_service'a.

This should fix gameplay aborting on switching to another app on iOS (and
apparently, on Android in some cases)
