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.
Fixed the code in DDTeleporter and made minor changes to other classes
that depended on those fixes. Ensured that PocketManager's load, save,
and unload methods are called appropriately and rewrote some of their
code. Made various changes in other classes (e.g. EventHookContainer,
PlayerRespawnTracker) to pass them references to DDProperties through
their constructors instead of having them rely on
DDProperties.instance() - this is a better programming practice in the
long run.
Renamed initialization methods in mod_pocketDim to make it clear that
they're called on events. Commented out command registration in
mod_pocketDim so that we can test DD as soon as PacketHandler is fixed,
without worrying about fixing the command classes.
Replaced several core classes from DD with new classes to enforce
integrity checks. Rewriting everything that depended on those classes is
a massive undertaking but it should simplify our code and prevent the
many bugs we've seen lately. The rewrite isn't done yet, just committing
my progress so far.
