disable pathfinding

Right now the nbt tag NoAI disable all movement even when pushed by an entity.

If there was a tag to turn of AI not movement so it isn't a statue then mechanic testing and commands could be given a new tool. This could be used for scripting and mods as the movement of the mob would be easily controllable. If this is a bug then please fix it because i think there should be 2 command one {IsStaue:0b},two{NoAI}.
