pull-requests: updated versioning support....
pull-requests: updated versioning support. - each pr version connects invalidated comments to it - in version list we show number of comments made on each version - show all outdated comments even for deleted files - linkify outdated comments to first one - added auto-collapse of commit range if they are more than 5 - styling changes, wide mode improvements
