v5.25.x Content Scheduling

API

• Feature: Major overhaul of how content items such as quests, magic hatching potions, and seasonal gear are made available. Extant items are now rereleased on a consistent, repeating yearly schedule, and there are no longer gaps between "Grand Galas"--one season's gear is always available at any given time.
