Return a URL ready to use in a generated HTML page from a URL that
is either absolute or relative to the webapp context path. That is,
if relative, it is relative to "http://server:port/thredds/".
<p/>
<p>For simplicity, all relative URLs are converted to URLs that are
absolute paths. For instance, "catalog.xml" becomes "/thredds/catalog.xml".

@param url the URL to prepare for use in HTML.
@return a URL ready to use in a generated HTML page.
