New category on friendlist: In Lobby

[Rizel]

So my idea is to make a new category on the ingame friendlist, for the friends who are in a lobby, but the game isn't started. This way I dont have to rightclick-> user info every time I want to check if I can follow my mate to the game.

Maybe a current match time after the player name would be nice too but I guess it takes too much resources from the servers.
