expansions to the pull review API

[GamerGirlandCo]

Feature Description

As of now you can create and delete reviews, but you can't update them (or comments within them) via the API. While you can respond to review comments via the web interface, the API doesn't provide that functionality.

I'd like to see:

• a PATCH endpoint for reviews
• a PATCH endpoint for a specific review comment
• a DELETE endpoint for a specific review comment
• POST endpoints to mark a file as "viewed" or "unviewed"
• a GET endpoint to fetch a pull review comment's children apparently there's no concept of parent or child comments
• a POST endpoint to reply to a pull review comment (see above remark)
• a POST endpoint to add a new comment to a review

I'd be happy to open a few pull requests to get these implemented :)
