Eidolon

 Changed:
  - Nerfed allure ritual to be about 50% as effective. This was intended before the initial release but it slipped my mind.
  - Added world generation disabling config settings. Use these instead of setting rarity really high or vein count to zero.

Fixed:
  - No value ranges on config values.
  - Crash when performing purification ritual.
  - Configured rarity for Eidolon structures being ignored.
