Beta 20220417-SNAPSHOT

Changelog:
 - Reorganized the listener registration method to register the listeners in alphabetical order
 - Added the IllOmen effect, which will apply a -25% debuff to a user's luck stat when they have the Bad Omen status effect.
 - Added the ability for Guardian lasers to inflict negative damage to a users luck stat.
 - Added a cache to the Luck class to store user values in the event that they have the Ill Omen debuff applied.
