Gold Rush Mode

[DanzaG]

1. Random number of secrets per level (we would need a minimum number)
2. Time limit per level (customizable, maybe we can have the tool running and that can force the game to transition to next level via the tool when time expires)
3. Stone = Easy = 1 Point, Jade = Medium = 3 Points, Gold = Hard = 5 Points. Maybe the tool can detect a pickup type (?) and track scores or just support manual scoring)
