[sv] Handling proper nouns when spell checking

Ok. Since spelling.txt is empty for Swedish, I thought that it was only supposed to be used locally, but now I see that it contains some words for other languages.

What is the standard operating procedure for contributing new words? Should I just add them to spelling.txt and then do a pull request? Or is it better to update the base dictionary (which I am not really sure how to do)? Perhaps they are occasionally moved to the real dictionary by a maintainer?

I think I read that one would need to add all variations of a word like conjugations and such. Is that correct?

Is it recommended to add names to the list, or does that bloat it too much?
