Add spell checker for documentation

[beregond]

Spell checker would find all typos in documentation in automatic way. Thanks to it people will be able to automatically check if all they wrote are proper words.

There already exists PR for that: ​https://github.com/django/django/pull/2354

This is neat, but as bmispelon asked, who is going to be curating - i.e. maintaining - the list?

It's a spelling checker by the way. A spell checker would be useful for a wizard. (I'm aware that this particular boat sailed long ago...)

I think I would probably be willing to look after this. I will try to review the PR soon.

EvilDMP - perfectly there is no need to add new words, but if it happens that someone adds word to docs, that is not recognized, and he notices the mistake, he should just add this word to wordlist, so then it is clear (in PR) that he added particular word. In the end developers that make changes SHOULD maintain the wordlist. (It is possible to add this check as test, so if someone will modify docs and this test will fail, he will either fix his typo or add this word to whitelist.)

Replying to EvilDMP:

Yes. Magic removal landed almost 8 years ago. Spell checking is no longer required.
