Metacat

Added "release" keyword to all metacat source files so that the release
number will be evident in software distributions.

Updated build process to now use a copy of the source files so that keyword
substitution can ocur before the build. This allows for substitution of
hardcoded values into the source before the compile. Currently, I am
using this feature to do the following:...

added Logout handling

clear lib dir from paths like xmltodb/lib/something.html

on "DELETE" added delete from xml_index table for a given docid
before delete from xml_documents, b' of foreign key in xml_index(docid)
to xml_documents(docid)

Changed exception handling mechanisms for DBReader

added createSQuery

broke up handleQueryAction into handleQuery, handleSQuery, runQuery and transformDocument

changed getRootNode method from public to private

replaced some deprecated methods with the new v2.2 of Java Servlet API
