Aaron Kimbrell 616ca46e95 fix(loot): activity reward coins use the reward's ChallengeRating level 
ActivityRewards coins were always read from CurrencyTable npcminlevel 1.
Live used the reward row's ChallengeRating as the npcminlevel, and level 1
when the currency index has no row for that level:
- FV foot races (ChallengeRating 4, index 1) gave 36 and 48 coins, which
  only level 4 (30-50) fits; level 1 is 3-5.
- Frakjaw's chest (activity 58, ChallengeRating 6) gave 250 each to a team
  of 2: its currency indices 123-126 only have a level 6 row (500), so DLU
  gave nothing.
- Quickbuilds, wishing wells and chests have ChallengeRating 1; survival
  and the shooting galleries have ratings with no row and keep level 1.
