Support of importing text files with CriticMarkup

I know is new, but it looks fantastic and it works with markdown. I’d love to be able to do some quick edits on the go in the CriticMarkup language and import them into Scrivener. Then have Scrivener make a snapshot of the old version automatically so I can roll back to it if needed.

I know this will become pretty ridiculous to do once the iOS app is released (or at least I hope it will), but it still might be something that people will like.
