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.
1. Fixed a couple of .info files2. Got rid of Ben's hack to always reload query files before doing a query mapping. He did this so you wouldn't have to reboot AOLserver every time you change query files. It was a short-term hack but unfortunately it looped virgin installs.3. Added code to the APM to make the "watch" feature work with query files as well as library files. This makes Ben's hack mentioned above unnecessary.
