RubyGems Mirror Tool

This gem can help you to full mirror of rubygems.org, it is an update to the old gem mirror command. It uses net/http/persistent and threads to grab the mirror set a little faster than the original. Eventually it will replace gem mirror completely. Right now the API is not completely stable (it will change several times before release), however, I will maintain stability in master.
