* [pr0gramm] implement infoextractor

* [pr0gramm] remove misplaced comment, uncapture regex-group

* [pr0gramm]: specify utf-8 coding

* [pr0gramm]: add trailing comma to lists for maintainability

* [pr0gramm]: ie only sets upload_date attribute

* [pr0gramm]: add video_id to title

* [pr0gramm]: more forgiving _valid_url regex
