Adds station prefixes for a few holidays
Holidays will now actually happen on their relevent days again, and not over a long period of time that kind of ruins the point of it being a holiDAY
Space Station 13's birthday will now actually announce how old the game is
*Chickens have been refactored to be entirely interchangeable
*Rabbits have been added, they will bounce around and place eggs, even in space!
*A Rabbit Suit has been added, and can be won from opening easter eggs!
*A Easter Basket spawns in the tunnels, allowing for easy carry of Easter Eggs!
*Easter Eggs will spawn in maintenance
*Easter Baskets also spawn in maintenance.
Holidays are now actual datums with procs and vars and everything.
Holidays run a proc called celebrate() when it's time to celebrate them. Currently none of them do anything but that should change, wink wink.
Holidays can now run for more than a day. The important ones, april fools, christmas, halloween, new years, and easter, all last at least a week. The idea is so people can celebrate christmas in game without having to, you know, actually play on fucking christmas. And also to put a time limit on how long stuff like the annoying spookoween closet skeletons will stick around so it doesn't overstay its welcome and become annoying as shit like last year.
The event SS now allows more than 1 holiday to run at a time. This matters for new years + christmas, easter + april fools, easter + 4/20, and any holiday that can happen on friday the 13th. The events get stored in a list that's only initialized if there's an active holiday so testing for potential holidays is still pretty easy.
Added more easter dates so we won't have to add more until 2040. The current batch run out in 2017.
