seat / sitting block or tile entity

I think it would be a good idea to integrate a simple system in the next version of mcreator 

do what we can transform a block into a seat, for example in the options of tile entity, or something else

there are many mods on mcreator, this function would allow to make more cosmetic mods, and to make usable seats, to create functional furniture in mods 

as a suggestion: we can for example imagine a box to caucher "is it a seat?" and when this box is checked, we can choose the height of the seat in y with the central point of the bloc.

it should work with 3D models, players could do a lot of decorating with it, such as thrones, armchairs, chairs, or even rugs on the floor...
