Exp in Crucible: in vials please

Right now we get experience in the Crucible but I think we should make this become experience vials instead and give zero “normal experience”.

This opens up a few things, including:

  • Repeated lvl1 crucible runs (a nice challenge!)
  • Doing the crucible at max level now gives something you can help other characters with
  • From here, it’s easy to add some adjusted reward options, in case people don’t want experience vials.
