Fixes #2367 and tweaks galaxy superfart

[KittyKathy]

:cl: Kitty Kathy bugfix: Galaxy superfart now works, but works a bit different that the original code. tweak: Galaxy superfart does not shoot off into a random direction it goes opposite what you are facing. tweak: Galaxy superfart will also move in a straight line until it reaches the end of the map. tweak: Immovable rods and their children now bump into whatever they spawn on. tweak: You can not galaxy superfart on any zlevel other than 1, it will instead go supernova if it picks that. /:cl: Fixes #2367. Am i doing this automatic changelog thing right? I have no idea what I am doing to be honest never used git before. Yes I tested this and it works unless something went horribly wrong when i was fooling around with the command line trying to get this to work. *Edited wrong issue number

once pyko's thingy is fixed it looks alright. Dunno why this wasn't doesn't a while ago.

Code looks good. The way we do changelogs is by creating a .yml file in /html/changelogs/

Have a look at example.yml in that folder to see how it's done

Looks good to me, would consider this to be a bugfix so it's good to merge once it gets an actual changelog

Changelog is good, merging as it's a fix
