Changed calls to canPlayerEdit() to pass hit.sideHit data with the
request. Also renamed several variables to make the code clearer.
Removed a custom implementation of the ray tracing call in BaseItemDoor
- we can use the built-in call from Minecraft there.
Moved the DimLink code out of NewDimData in order to reduce clutter
inside that class and made it a separate class, except for functions
that should only be available for NewDimData. Deleted IDimLink and
changed all references to it to use DimLink instead. DimLink is now an
abstract class, which achieves the same encapsulation and protection we
had before by having DimLink implement IDimLink from within NewDimData.
NewDimData has a new class inside, InnerDimLink, which provides it
access to special functions that would be dangerous to expose. This is
the same mechanism used to protect NewDimData's dangerous functions.
These changes are in preparation for adding more code for packet
handling.
More cleaning up errors and code. There were a lot of things that needed
simplifying. Rather than fix the 3 or 5 copies of the same function
throughout the code, I made an effort to use the same function and
delete its copies.
Created the BaseItemDoor class to hold all the basic door item methods
that don't vary between types. That helped cut down on fixing things.
Also renamed the door item classes to match their in-game names.
There is still a ton of duplicate code out there.
