added more methods of XmlTextReader. this increased the methods in the
* xmlreader.c include/libxml/xmlreader.h doc/libxml2-api.xml: added more methods of XmlTextReader. * python/libxml2class.txt python/tests/reader.py: this increased the methods in the bndings, augmented the test to check those new functions. Daniel
