	* plug-ins/python/diastddia.py : a new renderer implementation which 
	outputs Dia's native format, but restricted to "Standard - *"-objects.
	Initial version: buggy and incomplete (e.g. bug #576468).
	* plug-ins/python/Makefile.am : added to EXTRA_DIST
	* plug-ins/python/pydia-render.c : if the PyDia renderer does not
	implement an optional method just fall back to the base classes
	render implmentation. Also (try to) warn about missing, not optional
	methods with PyErr_Warn(), but can't find these messages yet.

	* plug-ins/python/diasvg.py : self.line_width was not initialized

	* samples/UML-demo.dia : converted to be readable, not a single line
	of uncpompresed XML.
