Minor improvements for "Lenght of Visits" view (patches included) #893

1. Since we use urldecode to safe decode labels, we need to use in labels "%2b" instead of "+" sign, because the last one urldecodes to regular space. See attached snapshot: "15 min" displayed, should be "15+ min". Simple patch:

    $time = intval($label) / 60;
    $plusXMin = Piwik_Translate('VisitorInterest_PlusXMin');
-   return sprintf($plusXMin, '+' . $time);
+   return sprintf($plusXMin, $time. urlencode('+'));
 }

 function Piwik_getPageGapLabel($label)

1. Labels in "Lenght of Visits" contain extra spaces after '-' sign (see the same snapshot, one of them is selected). Patch for English:

If you should accept this patch, I can prepare respective patches for other languages.
