[Teaser] Solid itr/kind: 14 (oh and platforming)

[YinYin]

Since it's based on collision between itr/kind: 14 and their bdy: all ther byds should end at the same same level (y+height-centery should be the same in all bdys).
Also for frames such as rowing and lying that doesn't have bdys a remote bdy at y: 1000 is used, along with a itr/kind: 14 in the solid object at the same height.

I think it may be much better if you only checked for object center and shadow size (>standing surface).

edit: actually only the object center point might be best. Would also be the best trade off for edge cases (at what point do you fall?).
