Par times/medals for levels

[Northadox]

Akin to PR3's campaign, levels should have custom par times players could shoot for; perhaps having just one par time or a gold/silver/bronze medal system. If a user sets medal times, there should be a clear check to make sure that clearing the level in that time is possible. If the level ends up in a campaign, admins could tweak the times if need be. Levels could also have saved world records, to challenge the best of players.
