Add wmode attribute to Mollom statistics SWF

Without this, DHTML menus, CSS menus, etc will be underneath the applet.

function mollom_reports_page() {
  $embed_attributes = array(
    'src' => 'http://mollom.com/statistics.swf?key=' . check_plain(variable_get('mollom_public_key', '')),
    'quality' => 'high',
    'width' => '100%',
    'height' => '430',
    'name' => 'Mollom',
    'align' => 'middle',
    'play' => 'true',
    'loop' => 'false',
    'allowScriptAccess' => 'sameDomain',
    'type' => 'application/x-shockwave-flash',
    'pluginspage' => 'http://www.adobe.com/go/getflashplayer',
    'wmode' => 'opaque', // Add this so DHTML menus and such will go OVER the Flash element
  );
// ...

Not always with embedding this way because is not valid XHTML (or HTML for that matter) but nobody really validates the back-end HTML so I guess it's okay here.
