Make comments for commits opened from pull requests appear in the pull request activity list

It's typical for us to review a pull request per commit. We try to create a clean commit history, so it's basically easier to view one commit after another. The main problem with pull requests here is, if you comment a line in a commit, this comment will not show up in the pull request activity.

This behavior forces us to have two views open. One showing the reviewed commit, and one the pull request 'Diff' view, where we have to add the comment.

Please make Stash remember, that a commit was opened from a pull request, and make the comments entered there appear in the pull request activity list.
