Command to fix all errors with the first suggestion

[dimateos]

I kind of already bumped #761 but my issue is not really about auto-complete although it could be nice.

I feel like the extension is missing a command to automatically correct all words to the first suggestion with a command, probably with some kind of log afterwards. The best idea I have is to add the top suggestion in the error/warning notice instead of "Unknown word."

So you could go through the list and if they make sense just automatically fix all of them. This way I would not need a log, but it maybe important to integrate undo in case something goes wrong.

As an example right now there is the command cSpell.addIssuesToDictionary
