Persistent crafts

[DerToaster98]

DoD:

• Crafts can be serialized to a YAML file and deserialized into crafts
• Crafts, that are serialized in a file but not "active" in the game, will be called "Sleeping crafts" here
• UUIDs of sleepign crafts must be reserved and respected when creating new crafts
• Sleeping crafts are deserialized one by one when the world they were in gets loaded, if possible, this should happen async (AT LEAST the reading of the file itself!)

TODO:

• Create branch based on the tte branch
• Add property, if a craft of a type can be serialized or not
  • If a craft is not serializable, add another option to delete the craft's blocks on world unload
• Implement Bukkits ConfigurationSerialization in BaseCraft and its children
• DataTag serialization:
  • Has to work for all primitive types and collections of primitive types
  • For more complex types, ConfigurationSerialization has to be implemented by the object where applicable
• Trackedlocation serialization and deserialization
• Serialization of the craft objects actual fields where it makes sense
• Hitbox serialization and deserialization
• CraftType serialization and deserialization => Toaster
• UUID reservations
• Saving crafts before world unload or server shutdown
• Reading crafts from files
• Adjustion of SquadronsReloaded
• Adjustion of TTE Additions
