* tree.c: improving some documentation comments
* xmlregexp.c: found and fixed a mem leak with python regression tests
* doc/*: rebuilt the doc and the API XML file including the
  xmlregexp.h xmlautomata.h and xmlunicode.h headers
* python/generator.py python/libxml2class.txt python/libxml_wrap.h
  python/types.c: added access to the XML Schemas regexps from
  python
* python/tests/Makefile.am python/tests/regexp.py: added a
  simple regexp bindings test
