feat(search): gh-style issue and pull request search tables

search issue and search pr printed rows without a header, showed merged
pull requests as closed and never said that more results exist. They now
show REPO#ID TITLE STATE AUTHOR UPDATED under a context line that counts
the matches and points at the next page, are also search issues and
search prs, take -s -L -A -l -m and @me, and use --until for --before,
which still works. Search results gain an author JSON field.
