[development doc updates]

[Fred Drake]

The development version of the documentation has been updated:

	http://python.sourceforge.net/devel-docs/


Almost to Python 2.1 release candidate 1 status.  This includes a variety
of small updates and a good bit more documentation on the PyUnit version
that will be included with the final release (new text essentially 
converted from Steve Purcell's HTML docs).
