Include Portuguese spelling check

[marcelobritox3]

I humbly request that the Portuguese spell checker be included, if possible PT-BR (Brazil) and PT-PT (Portugal).

That would be awesome. Looking forward to this iteration.

That would be fantastic.

Spellcheck for Language X

This post is to consolidate all the various requests to add support for spellcheck in language other than English. At the moment, we can’t leverage chrome/electron built-in spell check. @Licat made a pull request to electron to add support for interfacing the editor we use and the chrome’s spellchecker. When that goes through, we will have spellcheck in all languages.
