Integrate map interface with knb2 skin
Modifications to make JS search functions work in the knb2 skin.
New alternative KNB skin. Duplicates much of what is on the KNB site, butthis skin can work standalone with metacat (ie, you do not need the KNBweb site to be installed). Modified the resultset.xsl to do some thingsspecific to this skin.
