Although fields were created in DDProperties for Monolith spawning and
Rift generation, they were mislabeled as reading the "World Rift
Generation Enabled" property. I gave them proper names. I also changed
the fields and names to be more intuitive and rewrote the descriptions.
For instance, "MonolithSpawnDensity" is a misnomer because as density
increases, there should be more Monoliths, not less. Now the properties
clearly state how they affect a feature. I rewrote the conditions that
used each property to correspond with those simplified descriptions and
gave the properties default values that will match the generation rates
seen before.
I also made the rift generation code less cryptic and fixed a bug; there
was a check that compared if a dimension was a pocket dimension by its
name to prevent rift generation. That name check was wrong - it would
never work. Now we check if the provider is an instance of
pocketProvider. That will continue working even if we change the way
that pocket dimensions are named.
