Shows watermark on the page

See the message on bottom right saying "All content on this page is confidential"

This is shown using this macro


Note that we useĀ 

$generalUtil.escapeXml($paramMessage)

to sanitize the user's input and make macro safer for XSS vulnerabilities



## @param Message:title=Name|type=string|required=true|desc=Watermark message

<style type="text/css">
 .page_watermark {
   position:fixed;
   bottom:55px;
   right:15px;
   opacity:0.5;
   z-index:99;
   color:#FC0202;
   font-weight:bold;
   font-size:larger;
 }
</style>

<div class="page_watermark">$generalUtil.escapeXml($paramMessage)</div>
