Also show Battle.net MMR

As a new user migrating from Battle.net, there's no obvious way to gauge the difference in skill level in terms of MMR compared with Battle.net's MMR. On the website's Statistics page for MMR, the Battle.net MMR could shown in addition to the w3champions MMR (or on a new page). When viewing a profile (or anywhere w3champions MMR is shown, e.g. Match History or Replays pages), it would be insightful to additionally display the Battle.net MMR of a profile alongside W3Champions' MMR for that profile.
