AuthInterface...

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

added functionality to return the doctype of a relation in a relationdoctype tag. This information is now returned automatically in the resultset under the path resultset/relation/relationdoctype.

removed debug print statements.

added code for getting stylized related documents

allowed both indexing threads to run without interfering with each other.

fixed bug that caused a nullPointerException when a null resultset was returned.
