Cc remove sniff html table sort

replaced:
```javascript
if (!Browser.ie){
   rel = this.body.getParent();
   this.body.dispose();
}
```
with:
```javascript
	var readOnlyNess = document.createElement('table');
 	try{
 		readOnlyNess.innerHTML = '<tr><td></td></tr>';
 		readOnlyNess = readOnlyNess.childNodes.length === 0;
 	}catch(e){
 		readOnlyNess = true;
 	}
if (!readOnlyNess){
   rel = this.body.getParent();
   this.body.dispose();
}
```

Apparently we don't want to run that code in IE, I think it's because it creates some problem since IE's `TABLE` element has a different table object model, 
in order to know if we are working on this `special` object model we can use another peculiarity of the IE table object model which is the fact that for `TABLE` and `TR` elements the `innerHTML` property is readonly.
