Updated the NCEAS skin for various fixes: Rewrote the login XSLT to work correctly. Added a login status button to the page headers. Modified the header image to disable the global site search used on the NCEAS homepage. Removed former IFRAME cruft.
NCEAS skin changes: moved images into subfolder for organization, moved search javascript into search.js to cut down on replication. Modifications to nceas.css and midnight.css to clean up integration of Drupal theme.
Added submission of data files to the registry. New parameter 'hasUpload' can be set on a per-skin basis to enable the uploading of data objects to be associated with a metadata document. NCEAS skin is using this by default, to be changed in the future for other skins....
