Description

I read a comment on an Internet thread somewhere that mixed up "averse" and "avert" and began researching.
I found several contexts for both directions.

This PR includes a new Pattern, ContractionOfBe to go along with InflectionOfBe. There's several linters this could be backported to.

I have not yet looked into including "adverse". I'm not sure whether that would be better as a separate linter or making part of this one. If all three are confused with each other, they should be combined. If only two pairs are confused and the third pair is not (avert vs adverse) then separate is probably best.
