Port Frictionless Space (Goob-Station#464)

# Description This ports Simple-Station/Parkstation-Friendly-Chainsaw#46. This PR is something I consider a key feature adjacent to Space Wind Rework and its accompanying updates, and is an essential part of the space station experience. In practice, this weirdly enough makes being launched into space a bit easier to survive, since instead of needing to throw potentially hundreds of items, you can simply throw enough items to get started flying in the direction of the station and will eventually float back to the station. --- <details><summary><h1>Media</h1></summary> <p> https://github.com/Simple-Station/Parkstation-Friendly-Chainsaw/assets/77995199/5570ef35-16e2-493a-ac35-738f27751346 https://github.com/Simple-Station/Parkstation-Friendly-Chainsaw/assets/77995199/51fba943-8dce-4265-a9cc-7181155eb8de https://github.com/Simple-Station/Parkstation-Friendly-Chainsaw/assets/77995199/cd6c0511-2639-4e14-8160-426ba7f2ba73 --- </p> </details> # Changelog :cl: DEATHB4DEFEAT - tweak: Space has suddenly become less dense (objects don't slow down in space) - remove: Moths are unable to move in space - tweak: Moths have way better control in zero gravity environments --------- Signed-off-by: VMSolidus <[email protected]> Co-authored-by: DEATHB4DEFEAT <[email protected]>
