[creatorfromhell]

Rework the platform classes to be more API-based than hardcoded.

• Implement registries to allow third-party plugins to modify helper registries such as grabbing enchants, item names, flags, etc
  • Enchant registry
  • Flags Registry
  • Materials Registries
• Implement better item checks to allow checking for only specific information. I.e. checking for custom name, and not enchants.
• Implement ability for third-party plugins to add in item checks for plugins that utilize special data.
• Implement ability for third-party plugins to override functionality of various aspects such as override the built-in data serializers/deserializers.
