Add a daily statline to the home page.

Gets the following aggregate statistics about the past 24 hours:
    - the number of active players (day_active_players)
    - the number of games (day_games)
    - the total number of dm games (day_dm_games)
    - the total number of duel games (day_duel_games)
    - the total number of ctf games (day_ctf_games)

Cached by the hour, although it is not a terribly expensive query..
