Added the opportunity to generate the release notes for more than one component at the same time.
The Ant task now supports the 'fileset' inner XML element.
Some navigation pages are now being generated when the feature is enabled.
The javadoc-like selectors have been added to the CSS.
Multiple HTML pages are being produced, a little bit like javadoc does, so as to split the different release (present the generated HTML generated by the XMLReleaseNotes2HTML.xsl a bit like javadoc format, so as to output a single HTML page for each release).
