Summary information

We want backend views for the scoreboard.

For quests:

aggregates
Status (not started etc.) x (playing or not) => # Quests

For guilds:

aggregate guilds
Status (closed/recruiting/member) => # Guilds

Eventually:

N top guilds by # quests played, scoring...
N top players by # of quests played, scoring, guild scoring (Sum if many guilds?)
