Modified resultset to allow seperator <tr> to have an additional lead <td> element for styling NCEAS skin
Changes in login processing to match new register-dataset.cgi workflow: user must login before seeing the form, to prevent data loss. New template login.xsl provides simple redirection back to register-dataset.cgi.
Added a refactored resultset stylesheet that allows skins to override the container format to not use iframes. The continaing skin can now import resulttable.xsl and call the result table template directly.
