Enable future without horror

See this really good critique for why: https://www.reddit.com/r/expeditionrpg/comments/cozj4x/playing_with_horror_scifi_thoughts_on_compounding/

We'll need to:

• tweak the app so that they aren't tied together in content selection
• tweak the quest creator so they aren't tied when publishing
• tweak skill checks to not use light / dark if horror isn't enabled
• make sure setup and combat instructions, and combat properly respond to just Future (aka no mentioned of Persona or Influence)
• review future cards for those that rely on persona without alternatives - if those exist, we'll have to provided future & !horror instructions for what to do in the app + FAQ, and update those cards in the sheet so that they're fixed for future print runs
  • example: Ignore quest actions involving Persona, you may re-draw loot that mentions Persona
• update website store descriptions such that future doesn't require horror

Optional: Scan through quests that require The Future for any that don't mention Horror / Persona / Influence, and remove their requirement on The Horror
