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. Added a new attribute to the .info file which tells the bootstrap installer whether or not a package is part of the acs-core. Only acs-core packages are now installed during the initial bootstrap install of the system.
2. Fixed a dupe query name problem in a couple of queryfiles. The problem is not with the dispatcher but with the extractor, and for the moment it is just easier to kludge the resulting queryfile than fix the extractor.
