Fix Village Loading Doors fix, add config option, hopefully fix farms

The patch was previously applied wrong, and still caused chunk loads.

Now, we will prevent it again, but also added a config option to
disable this optimization.

However, I also updated it so that doors are not removed if the chunk
the door is in is unloaded, so this should avoid breaking farms.

Fixes #1506
