Title: Small fix for parsing tracker URL.

Fixed and improved some small problems in converting tracker URL. All tracker URLs will be converted into a uniformed format listed as follows:

(1) HTTP tracker URL should be: http://:/
(2) UDP tracker URL should be: http://:

This operation not only validates a given tracker, but also removes unnecessary duplicates.
