Description

I kept making more and more linters to fix wrong prepositions so I finally decided they should be their own LintKind.
I was going to call it WrongPreposition but there are a couple of other preposition-related lints so I ended up choosing Preposition over Prepositions... but maybe you disagree? Let me know!

I changed the LintKind of all the Rust and Weir rules that seemed applicable.
