Renamed IDimDoor.placeDimDoor() to placeLink(), since that's what it's
actually being used for in our doors. Saying it places the door itself
is confusing.
Improved our code for checking whether an entity in contact with a door
should be teleported. Now the check works better, works for Minecarts,
and is more readable. It also ignores particle effect entities.
Got the Transdimensional Trapdoor working again. Renamed the file to
TransTrapdoor and trimmed off unnecessary code - BlockTrapDoor
implements a lot of the necessary logic. Implemented IDimDoor for
clarity.
Updated BlockRotator to check if a block is an instance of DoorBlock
instead of checking for BaseDimDoor - since we changed BaseDimDoor to
derive from DoorBlock, the latter check is no longer needed.
Deleted PlayerRespawnTracker and removed all references to it - we
weren't going to use it anymore anyway. Renamed IDDoorLogic to IDimDoor
- abbreviating the "Dim" as D next to the standard I for Interface is
confusing. Renamed DDoorBase to BaseDimDoor and made it into an abstract
class - that's effectively what it was supposed to be. We should be
declaring methods as abstract rather than using empty ones. I renamed
the class because the convention for naming abstract classes is to start
the name with Base. Cleaned up code in other files.
