Returns a link <i>from</i> the URI stored in the provided OpenCms user context
<i>to</i> the given <code>link</code>, for use on web pages.<p>

A number of tests are performed with the <code>link</code> in order to find out how to create the link:<ul>
<li>If <code>link</code> is empty, an empty String is returned.
<li>If <code>link</code> starts with an URI scheme component, for example <code>http://</code>,
and does not point to an internal OpenCms site, it is returned unchanged.
<li>If <code>link</code> is an absolute URI that starts with a configured site root,
the site root is cut from the link and
the same result as {@link #substituteLink(CmsObject, String, String)} is returned.
<li>Otherwise the same result as {@link #substituteLink(CmsObject, String)} is returned.
</ul>

@param cms the current OpenCms user context
