E.g.

• ColdParachuteEntity and GoldenParachuteEntity can be deleted and AbstractParachuteEntity can be renamed to ParachuteEntity, then the entity types for COLD_PARACHUTE and GOLDEN_PARACHUTE can just ParachuteEntity.
• Golden and Blue Swets should be split into separate entity types.
• Unsure if this should include Moas. Using this idea instead of MoaTypes may allow addon modders more capabilities here when they can just make their own Moa classes. (EDIT: This wouldn't allow an easy way to specify stats so maybe this is not a good idea, unless it can be done through their entity type register).
