OUTDATED/ABANDONED, USE /create passenger COMMAND

This mod allows you to make boat contraptions with the Create mod... in a weird way.

This mod does not really require Create, however, it is almost useless without it, so, i mark it as Required Dependency.
This adds a tool to allow the minecraft and its contraption to be seated in the passenger seat of the boat(or any other entity). I don't know why you need this, but, nevertheless, why not?
At the moment, In acceptance mode 0, the version is unstable, be sure to make backups of the world. In acceptance modes 1 and 2 the mod is quite stable.

Acceptance mode command guide:

To increase stability, I added a command that allows you to set an Acceptance Entity Mode(/setacceptancemode). By default, it is set to 1. It allows you to set which mobs can be used in contraptions.

On servers, I recommend setting it to 1 or 2.

It works on tags boatcontraptions:contraption_convertable and boatcontraptions:always_acceptable_entities for first and second mode, respectively

If mode 0, or mode <any other except than 1 and 2> is enabled, all entities can be used in contraptions.

If mode 1 is enabled, only this list can be used in contrapions:
All vanilla living entities, boats, minecarts and armor stand

Exceptions:
Dragon
Ravager
Elder Guardian
Endermite
Ghast
Hoglin
Zoglin
Polar bear
Plufferfish
Enderman
Giant
Iron Golem
Player
Shulker
Wither
Wither Skeleton

If mode 2 is enabled, only boats can be used in contraptions.
