Made progress on overhauling and prettifying our commands. There are
still more changes to be done for this to be functional. I need to do an
intermediate commit because I want to merge in recent changes by Steven.
Fixed null DDProperties reference in DimData. Changed the code so that
it requests an instance in each of its functions instead of relying on
loading a reference when it's first instantiated. I'm not sure how the
null references are slipping through, that shouldn't be possible.
Moved all configuration variables from mod_pocketDim to DDProperties
(formerly DimDoorsConfig). Changed property names to be clearer in
config file, modified some comments, and generally cleaned up the config
file. Fixed some missing properties and variables that were reading from
the wrong properties. Modified the order in which mod_pocketDim
instantiated some of its static fields so that they would load after
properties are read. Almost all classes load after properties are read.
Fixed indentation across various files and replaced references to
properties in mod_pocketDim with references to DDProperties.
