Look at:

• SynchedEntityData
• ServerEntity.sendDirtyEntityData()
• ClientboundSetEntityDataPacket

Create a class SynchedCapabilityData which will have similar function to SynchedEntityData but its purpose will be usage in our capabilities to allow for data syncing without creating tons of packets.

Ideas:

• Might be possible to have a CapabilityDataEntry class which can store basic values like ints and booleans which can be passed into a catch-all packet to send that data across sides to sync.
