Add xmldom parser

Integrating this module allows us to do HTML/XML parsing under Node.js
(there is no built-in support for Node.js; we can already do HTML/XML
parsing in the browser). The implementation chosen is pure JavaScript,
and will work in all configurations of TiddlyWiki.

+
+A JavaScript implementation of W3C DOM for Node.js, Rhino and the browser. Fully
+compatible with `W3C DOM level2`; and some compatible with `level3`. Supports
+`DOMParser` and `XMLSerializer` interface such as in browser.
+
+Install:
+-------
+>npm install xmldom
+
+Example:
+====
+```javascript
+var DOMParser = require('xmldom').DOMParser;
+var doc = new DOMParser().parseFromString(
+    '<xml xmlns="a" xmlns:c="./lite">\n'+
+        '\t<child>test</child>\n'+
+        '\t<child></child>\n'+
+        '\t<child/>\n'+
+    '</xml>'
+    ,'text/xml');
+doc.documentElement.setAttribute('x','y');
+doc.documentElement.setAttributeNS('./lite','c:x','y2');
+var nsAttr = doc.documentElement.getAttributeNS('./lite','x')
+console.info(nsAttr)
+console.info(doc)
+```
+API Reference
+=====
+
+ * [DOMParser](https://developer.mozilla.org/en/DOMParser):
+
+	```javascript
+	parseFromString(xmlsource,mimeType)
+	```
+	* **options extension** _by xmldom_(not BOM standard!!)
+
+	```javascript
+	//added the options argument
+	new DOMParser(options)
+	
+	//errorHandler is supported
+	new DOMParser({

+		 * locator is always need for error position info
+		 */
