* Adjust the old speed calculator to include end to end RTT data in its
      estimates, and use that as the primary speed calculator again.
    * Use the mean of the high capacity speeds to determine the fast
      threshold, rather than the median.  Perhaps we should use the mean of
      all active non-failing peers?
    * Updated the profile page to sort by tier, then alphabetically.
    * Added some alternative socketManager factories (good call aum!)
