update to press release component of sample website

Browse Source 
- adding sub navigation to press release page to generate navigation by category in xsl (demoware for virgin)
- adding sub navigation to index.jsp to generate navigation by category (also demoware for virgin)
- cleanup of freemarker template and all sorts of fancy xpath stuff
- putting the company footer data type directly in the press release.xsd rather than having a seperate xsd.  while this makes the form creation process a bit confusing, it demonstrates why the root element name field is there, and minimizes files.  also forced me to clean up some major overloading of pr:company_footer.

changes to form data functions
- renamed getXMLDocument and getXMLDocuments to parseXMLDocument since it's now returning the document element rather than documents so that xpath traversal works (also since the document is completely useless in the context of templates)

adding bsf.jar so that hopefully someday i can write extension functions in javascript within xsl templates (couldn't get it to work).
