This fixes jQuery bug #6863: Faster getText by using Array.join('') instead of += for string concatenation.
Based on comparisons of Array.join vs string concatenation on jsPerf this change may have a negative impact on performance in Chrome, Firefox 4 and IE8+. It will have a minor performance benefit in IE6 and IE7, Safari (as of version 5.0.5) and Opera (as of 11.10).
