add nether vine placement checks for top and bottom of nodes (#4129) 

This adds placement checks to weeping and twisting vines, weeping vines should only be placed on bottom of nodes and twisting vines should only be placed on top of nodes.

Most of the work for this was done by JoseDouglas26. This was made with their permission, I just had to tweak the code a bit to get twisting vines to place right. Thank you Jose!
