#369364 Views integration: fix non-XHTML markup when displaying fields with the 'group multiple values' option.

now nests a div for multi-value fields within the span tags that views creates for inline fields within a view.

For example, below is some HTML generated from a view of a number of authored works. Each result row displays the work title and then the author inline with :: used as the separator. Since the fields are displayed 'inline' in the views configuration, each field is surrounded with span tags. But - field-field-author-nid can have multiple values, so it's surrounded by a div tag. Thus - there's a div tag within a span tag. This problem is generated from a combination of the views and cck modules.

 <span class="views-field-title">
    <span class="field-content"><a href="/node/38" title="Interview with XX" alt="Interview with XX">Interview with XX</a></span>
  </span>
      ::   
  <span class="views-field-field-author-nid">
                <div class="field-content"><div class="field-item">John Smith</div></div>
  </span>
</span>
