Animated cyborg transformations

- Adds Iatot's animations from standard cyborg to other cyborg modules.
- I did some editing to engineering, medical, security and mining cyborgs. Will post gifs on forums.
- Toiletbot (Service borg Kent) not included.
- Renamed some cyborg sprites in robots.dmi so they make more sense/ are easier to work with.
- code copy-pasted from code/datums/spells/ethereal_jaunt.dm.
