changed action's value:

Modified stylesheets to use the default.css file from the new KNB web site.
Also, provided a new resultset.xsl that represents a simple freetext query
of the KNB data repository. Updated build.xml to relect the location of the
new css stylesheet.

Began work on new UI for the KNB web site. It will be the main query
interface from the KNB website.

Fixed the LDAP authentication adapter (AuthLdap.java) so that it now looks up
the distinguished name for a user before attempting to do authentication.
This is because the user's distinguished name can sometimes be based on
their uid attribute, but sometimes be based on their cn (common name)...

merge AUTH_LDAP to the main branch

clear System.exit(0) within the static block

Fixed typo in stylesheet.

More user interface changes to the HTML MARINE interface. Minor
rearrangement of columns, some link changes.
