BUG: better support for paper.yml generator-settings

[Powen Cheng]

Can you please have a better support of these settings? I only tested a few but I already found with temple: false - I still get them regenerate in the world.

generator-settings:
  canyon: false
  caves: true
  dungeon: true
  fortress: true
  mineshaft: true
  monument: true
  stronghold: true
  temple: false
  village: false
  flat-bedrock: false

EWG does not support custom spigot/paper settings, use the configuration files found in EWG. (per world settings is located in each world folder)
