This adds the entire framework needed for the clowns to work.
Clowns work with three variants:
Normal, friendly, every tuesday clowns.
Big, hostile, space clowns.
And AdminBus Clowns.
The Honk Elemental is here and it spawns eggs that act like lost drone pods. If you're a ghost getting sucked in, you'll be able to choose from any of the normal clowns. This is for a special event that'll happen off station.
There are some unused sprites for clown mobs I haven't gotten coded up. These are all in the "TG clowns" dmi. They will be finished at a later date when I can get them to do their special tricks.
TODO: Edit gutter map, make extra clowns, make clown map.
