Update to XSS-Harvest

Minor update, with improved redress functionality (thanks to @Openwatch), and a check to see whether the script has already been loaded (prevents duplicate keystrokes if the infection string is echoed more than once by the vulnerable application).

Download the new version from Cyberis' github repository here.
