[1.7.4] Outside of vault is no-teleport

[Horken]

At least some vaults have a no-teleport zone on their outside. I just encountered and verified this with the small vault which has a pickaxe outside the door and a bunch of infusions inside. You cannot teleport onto a tile directly surrounding it or the tile in front of the door. You can teleport away. I remember this also happened with some other vault at the minimum.
