Helper method for escaping XML, used by GGUS sync

For having a valid XML, in text and attribute values, you need to escape ASCII characters like:

"

  <

 >

&

How

All text in an XML document will be parsed by the parser, but text inside a CDATA section will be ignored by the parser. So, instead of replace this four characters we put the text inside CDATA using the script include 'String-Util':

..
  /**
   * Escape the following characters to be transported over the network with XML
   *  - >
   *  - <
   *  - "
   *  - &
   */
  escapeXML: function(text) {
    return '<![CDATA[' + text.replace(']]>', ']]]]><![CDATA[>') + ']]>';
  },
..

Then, we used this method in GGUS sync to escape short description, solution and comments:

..
gs.include('String-Util');
var stringUtil = new StringUtil();
..
s.setParameter('short_description', stringUtil.escapeXML(current.short_description));
..
