Revert "Add lowercase of åäö in entityMap"

[joestringer]

This reverts commit ef20262.

These characters were already included lower in the file in the sorted
order for lower-case runes.

Including duplicates like this causes issues in Rhino 1.7.12:

Property "auml" already defined in this object literal.

Fixes: #83

Thanks! I may need some time to double-check before merging.

I suspect that the issue could have been avoided had we started using using eslint or a derivative such as standard, as discussed in some other issues.

Awesome finding!
Just checked, the removed keys are existing below.

(introduced by PR #23)

I have some nits coming up.

[brodybits]

Thanks for the contribution. I do have a few more nits for the future:

• The test coverage of lib/entities.js is very spotty. I just raised PR test European HTML entities #86 to start testing the affected entities, to gain some extra confidence, and it does look good with this change.
• I noticed that the change was contributed from the master branch of the fork. It is generally recommended to contribute changes from another, temporary branch instead, to avoid likely divergence. PRs are generally merged as squash commits in this project.

As I had implied before, it is not very nice when a revert would undo formatting cleanup. But I think taking it out would make it not a truly complete revert. I think PR #85 solved it by simply getting rid of the useless line.

Once we have better test coverage, Stryker should show us if we have duplicated string entities again.

On a positive note: kudos for putting the information into the revert commit itself. This should make it easier for people to understand the rationale without having to dig through GitHub.

Thanks again for the contribution!
