[READY] SNAKES! (#34724)

* actual phobia created

* (LAST ATTEMPT) Adds Snakes

🆑 Togopal
add: Snakes! They hunt vermin on the station!
add: They can be purchased in cargo.
/🆑

Mice can be a problem in late round random events, and I figured releasing a bunch of snakes in maintenance would be a more long-term solution than constantly running around with a crowbar when you hear them.

Now with updated sprites!

(I apologize heavily for uploading this three times. I was unaware I was using an older fork, as this was my first attempt at modifying the code.)

* curator gets trauma! and fixes to snek trauma

* fixes the travis error

silly frog

* Reduces the cost of a normal snake crate in Cargo. Adds retaliation to snakes upon being attacked, removes venom from regular snakes.

I A

* quick fix

* quick fix 2

* fixes the cargo contains = list

* go away TRAVIS

* changes the name of the snake cargo crate of regular snakes to avoid confusion

* Updates how some snake mechanics works

Makes them actually retaliate, code is still sort of buggy though

* Some orange fixes

* Fix snakes on this motherfucking plane

* The thing oranges said
