This patch is twofold consisting of bugfixes and feature-additions

Bugfixes
========

- fix typo in _new() functions that leads to 100% segfault [if (!found) *found = 0]
- make sure that the "type" attribute is set in every case
- do not call xmlFreeNode() in domxml_unlink_node() because unlinking != deleting;
  (since one could still add_child() a node that was unlink()ed!)

- fix add_child() to handle XML_TEXT_NODE coalescing. i used a different
  approach than one can find in current (2002-02-10) CVS. my approach does not
  make it impossible to keep references to domxml_nodes around and reusing them
  after add_child(). for details, read the big comment in
  domxml_node_add_child() in my patch.

- add domxml_node_has_attributes() to the list of domxml_node methods as
  "has_attributes"




New Features
============

- new functions:

    object domxml_text_node(string content)     
		create a new text node

	bool domxml_replace_node(int oldnode, int newnode)
		replace oldnode with newnode. you may also call it using
		$this->replace_node($oldnode) (e.g. "this" will be "newnode").

    object domxml_get_root(void)
		return the current root element of a document

	bool domxml_set_root(int domnode)
		set domnode as the new root element of a document
