Python parser for SN

[Ben Elliston]

   This patch contains a python parser and syntax highlighting for
   python.

Fantastic!  Thanks for doing it.

   Since I don't have automake on my development system (I use NT), i had
   to write Makefile.in's and Makefile.am's by hand.

Note that it's not necessary to run Automake and Autoconf on the system
you're using.  If you move your tree to a Unix system with these tools
installed, you can run it there.  Autoconf and Automake work fine under
Cygwin, by the way.
