updated BarracudaDiscRack!

I've updated BarracudaDiscRack to work with the latest XMLC-2.2 and the 
latest Barracuda jars.  It also has deferred parsing enabled so you can 
modify the .html files under the WEB-INF/classes directory in the same 
package as the XMLC classes and see your changes immediately.

The docs may be a bit out of date.  I haven't really checked them 
yet.  Installation is quite simple.  If you've been using
"ant catalina-install" to install Barracuda to Tomcat, then you'll be happy 
to know you can do the same thing with BarracudaDiscRack.  Just remember to 
set up a user which has access to the Tomcat manager app and then either 
modify build.properties in BarracudaDiscRack/src or, better yet, create a 
.build.properties in $user.home and add the information there.  It will 
override the properties files that come with BarracudaDiscRack.  Same goes 
for Barracuda and the contrib apps.  No other mods are needed.  It will 
just work :-)
