Merge entity mounts branch to master (#589)

* Initial support for entity mounts*

* This only works for viewing other players on mounts/vehicles. Currently, mounting on vehicles through Geyser with bedrock does not work at all, though, you can see other Java players on mounts just fine.

* Fix Bedrock player mounting; add minecart offset

* Remove debug code

* Fix boat animation

* Remove debug code

* Add notice of possible steering flip

* Add translator for PlayerInputPacket

* Upload WIP code for BoatEntity.java

* Add animation for rowing on Bedrock side

* Clean up debug code, start on boat movement

* Add notice about flying horses

* Rename BedrockPlayerInputPacket.java to BedrockPlayerInputTranslator.java

* Delete BedrockPlayerInputPacket.java

* Use Translator Annotation again; Thanks to LegacyGamerHD

* Upload ineffective mount-on-login code

* Upload current changes with no debug code

* Change case where applicable

* Change Integer[] to int[]; Change schedule() to execute()

* Don't use Thread.Sleep() and instead call itself again

* Fix players not being linked on login/chunk load

* Little changes

* Minor improvements/fixes to boats

* Remove empty file

* Fix horse flying.

* Various entity mounting fixes

* Add mounting offsets for skeleton and zombie horses

* Another round of entity mount-related fixes

- Add offsets for skeleton and zombie horses (Thanks to tester DirtNasty)
- Boats can now be placed in survival (Thanks again to tester DirtNasty)
- Boats and minecarts can now shake

* Add translating for ServerVehicleMovePacket

* Cleaning up

* More cleaning up

* Add interactive tag support for mountable entities

* Boats move far more nicely

* Add horse heart visuals

* Update interactive tags
