See #3694
* WARNING! Incompartible change! Now newtag=n.T.newtag do not creates new tag
but only returns existing one (if possible). If you need to create tag use
either .NT. method or attribute set (i.e. n.T.newtag=something).
* Added CDATA extracting method to xml node.
* added xmlns safety check
* Fixed node attribute deletion with "del node[attr]" syntax.
* Ordering fix for when addChild and addData are used on the same node (may increase memory usage, might need to watch for that)
* Fixes for children node fetching, still not perfect, but much better
