Subject: game: Send a game-info event when a client connects
X-Git-Url: https://git.cworth.org/git?p=lmno-server;a=commitdiff_plain;h=ee64666099c0401afdc1e51fe378359f943d3f69

game: Send a game-info event when a client connects

This is in the generic Game class so all games will get this
functionality. This will allow clients to be able to display the
game's ID and URL so players can invite friends.
