Title: Fixes an ender pearl clipping exploit with blocks that occupy less than 1 block in width or length

After quite a bit of thorough testing, this seems to be an efficient way of fixing an exploit allowing people to go through most importantly, glass panes, which are often used as windows. I'd be happy to pm you the re-creation conditions for the exploit. I know the setTo might seem a bit scary but from the extensive testing I did it causes almost no visible difference then what ender pearling into a solid block would be like.
