Arancino's Night Journey

While I was at it, I configured everything that needed configuring, fixed a great many bugs, swapped out a few mods, reduced the spawn rate of some monsters that were causing lag, added bosses to the Undergarden, replaced "Even Better Nether" with three other mods that offer vastly better compatibility, increased the spawn frequency of numerous structures, and added more spawn locations across various biomes for a dozen or so structures.
