//DOORS//
~~~~~~~~~~~
Just a door, you know how their made. The reinforced and ironbark doors
can be opened by hand, while the steel door is just a stronger iron door, that
needs redstone to open.

Fortunately to you: Zombies and villagers are reaaallly stupid. so stupid in
fact: they don't even know that these objects are doors.. really. so they will
not bother you.

Yeh. by really stupid.. I mean the built in ai for path finding is real stubborn
they only interact with vanilla wood doors. by id. nothing else.
