Added the onEnable method. Added the command used for manually
activating events. Added the Acid Rain event. Added Apocalypse event.
Added MineralRain event. Added RandomTeleportation event. Added the
Strobe Light event. Added so that once every day an event happens and
the even is randomized and so is the time of the event. Sorry I only
commited at the end because I read that I need to commit every fifteen
minutes like fifteen seconds ago so I didn't know. But I swear to god
all the code in this project is mine.
