Ctrl+click redirects in current tab for outgoing links

[Bahm]

In all major browsers, ctr+click opens a link in a new tab, but on the Nim website it also redirects the current tab if it's an outgoing link. The same happens with ctrl+enter (when a link is selected).

The problem occurs because of the following line in the code below: 'hitCallback': function(){document.location = url;}

    (function(){
      function setTracking(a) {
        var url = a.href;
        a.onclick = function() {
          if (typeof(ga) !== "undefined") {
            ga('send', 'event', 'outbound', 'click', url, {
              'transport': 'beacon',
              'hitCallback': function(){document.location = url;}
            });
          }
        };
      }

      var a = document.getElementsByTagName("a");
      for (var i = 0; i < a.length; ++i) {
        if (a[i].hostname != location.hostname &&
            a[i].getAttribute("target") !== "_blank"
        ) {
          setTracking(a[i])
        }
      }
    })();

I'd say we can remove this tracking. I don't think we use the data from it really.

@yglukhov added it a while back IIRC, let us know if you have any objections :)
