Metacat

Modifications to the registry to support the new ESA skin. Factored out some of
the configuration-specific code into properties that are set in the various
cfg files in the skins. New properties in the cfg files are lsite, usite,
showSiteList, showWgList, showOrganization. These now need to be set in every skin...

added target=_blank to generate UI links

pointed knb2 resutls page at production whippet on port 8080 of nebulous, instead of dev version on 8090

Changed path for eml.xsd stylesheet.

Added eml2.0.1 specific code in /style file

Changed index.jsp to fix bug 1232 so that it works on knb.ecoinformatics.org.

Added code to add and remove cookie from the index.jsp when a person logs in or logs out.

Modifications to make JS search functions work in the knb2 skin.

New URL for metacat in settings file.

New alternative KNB skin. Duplicates much of what is on the KNB site, but
this skin can work standalone with metacat (ie, you do not need the KNB
web site to be installed). Modified the resultset.xsl to do some things
specific to this skin.
