Changed SchematicLoader so that schematics that have entrances that are
not facing North will still be rotated properly. This involves a
workaround for transformMetadata() since it assumes schematics are
always saved "facing" North.
I've tested this and it's working perfectly, with one exception. If you
create a rift with dd-rift to a dungeon that wasn't saved pointing
North, the rifts sometimes appear beside the player, instead of in the
block where the player's head is. Sometimes you'll appear in the dungeon
facing the right way. Other times, you'll appear inside a wall adjacent
to the entrance or near the entrance facing the wrong way. I have not
managed to narrow down why this happens.
