Number of total BitBucket repositories, non-forks and forks

;;; This counts projects and forks from BitBucket.org.
;;; It starts with the repositories list sorted by forks.
;;; Then, it scraps for the count of forks, and it sums it,
;;;plus 1 for the original repository.
;;; When it finds a repository with zero forks, it sets a flag
;;;so that it calculates the remaining from the number of
;;;repositories per page.
;;; It actually calculates the remaining pages but the last, so
;;;the last page is fetched and scrapped for a more accurate sum.
