Image Emojis: Emojis in chat

Changelog:

• Added more flexibility by changing enforceResourcePack to enforcementPolicy in config.yml:
  • NONE - The resource pack won't be loaded on join. This option can fit servers where players prefer to download the resource pack manually
  • OPTIONAL - Players can decline the resource pack from loading on join
  • REQUIRED - Players are forced to play with the resource pack
