Add partial implementation of handling disconnects while playing via network

- Reverse the order of client list - Add 'game in progress' room state to implement support of in-game disconnects notification

- Add forgotten PirateFlag map to list of installed maps - Add each preview.png to installation

- Remove deprecated stuff - Add a preview to each map, so switching is now 100 times faster

- Set focus to dead hedgehog - Switch from rooms list page to net page when disconnected from server

Clients send roundfinished message to server when the round is over
