- changed the XML parsing throughout to go through a simplified API to later upgrade XML parsing in a central place. - updated support for ns_xml 1.4, and added work-arounds for previous versions. - added installer check for ns_xml compatibility at boot time.
first attempt at doing XML parsing using ns_xml instead of the Tcl XML stuff. Not sure yet if this is faster, although we expect that it will be. Note also that there seems to be a bug right now in ns_xml where an XML comment will screw things up, so I've added a quick prepare function that takes out comments before XML parsing... I'm not happy about that.
