Cleaned up the indentation and empty lines in DungeonHelper. Set
metadataFlipList and metadataNextList to have generic type Integer,
since they're used to store block IDs. Whenever possible, we should
always be using parameterized collections instead of leaving their types
unspecified. I'd like to fix up the schematic HashMap in the future -
unless it's necessary, we shouldn't be storing values of various types
in that collection. Strongly typed variables or a class with the
appropriate fields would be much cleaner.
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.
