Redirects Wikipedia to use the good (pre-2023) skin.
Brings back the old Wikipedia style.
More specifically, it simply appends ?useskin=vector to the URI and every wikipedia.org link.
If you wish to use another skin (for example 'monobook'), edit the skinchoice constant. (For more about skins: https://en.wikipedia.org/wiki/Wikipedia:Skin)
Largely based on Ksir's reddit redirector code, all credit goes to him. https://greasyfork.org/en/scripts/40897-old-reddit-please
