Converted Schematic Doors

Converted the doors in our schematics into doors from DD. Also converted
mangled block IDs into Fabric of Reality and wiped all tile entities
from Steven's schematics to remove prefilled chests that had been
included somehow. Changed DungeonSchematic to expect mod doors now. This
means we can include Vanilla doors in our designs and they will not be
converted anymore.

This process was done by automatically re-exporting all of our dungeons
multiple times, so it serves as a good test that importing and exporting
are working properly. We confirmed by thorough testing that our
schematics load properly into WorldEdit. MCedit, unfortunately, does not
handle them right. We believe this is a bug in MCedit, NOT with us.
