Fixed Door Bugs

Fixed the bugs that caused doors not to appear right in dungeons. First
there was a bug with filters that caused them not to replace blocks
properly. I made some changes to SchematicFilter and its derived classes
so that the implementations are a little more intuitive. That should
prevent those bugs in any future derived classes. Then doors wouldn't
rotate properly. DD was never designed to rotate dimensional doors. I
added code to BlockRotator for that and shifted some code from
DungeonHelper to BlockRotator. More coherence, less coupling!
