[XML-SIG] New parsers in 4XPath and 4XSLT

[Jeremy J Kloth]

The new generated parsers in XPath and XSLT are now created in a more
factory-ish method.  The parsers are now referenced from:
xml.(xpath|xslt).parser   This allows for the changing of parsers easily.
To create a runtime parser, call parser.new().  And to parse expressions
simply use the parse() method on the created object.

Hopefully this change will help ease the integration into PyXML.
