adds crushed can, jelly doughnut, and shipping container random spawners (#78444)

## About The Pull Request
i got bored so i made some new spawners, mainly for mappers but maybe an
admin will use them too. pics here:

firstly, this adds crushed can spawners, for if you want a random
crushed can sprite in your map, and don't really care which it is.
if you _do_ care, however - you can set the var/random_icon field on one
of these to 0, in your copy of strongdmm. then just change the icon
state to whatever specific can design you'd like it to be (ie:
"wellcheers")
here you can see a few of them in action

secondly, this adds doughnut, jelly doughnut, and slime jelly doughnut
spawners - pictured below
these use a weighted list based on flavor - more down to earth flavors
are more common, while more interesting and unique flavors like bungo
and blumpkin are a bit rarer.

thirdly, this adds a shipping container spawner. this one uses a
weighted list so the super obvious syndi corps are rare, less obvious
ones are less rare, and regular corporate ones are common. here you can
see a few.

## Why It's Good For The Game
more flexibility for mappers, more dynamic spawns... what's not to love?
