Mailto opens in _blank

[alexwasner]

Expected behavior:
User clicks href="mailto:name@url.com" and users email client opens.

Current behavior:
User clicks href="mailto:name@url.com" and new _blank window along side the users email client.

My current fix although I have not done extensive testing
in Application.js

      isMail = url.indexOf('mailto:') > -1 ? true : false;
      if(isMail){
        target = '_top';
      }
