NsisXML plug-in (by Wizou)

WARNINGS!!!

1. The name of this plug-in conflicts with Joel's nsisXML.
2. It is a known issue that MEMORY IS NOT CORRECTLY RELEASED after using this plugin. (and this probably wont be corrected) It usually won't matter much if you deal with small XML files, but if memory leaks is a bad issue for you, then don't use nsisXML.
