[Distutils] Patch for PEP 241

[Andrew Kuchling]

I've got a preliminary version of the patch to implement PEP 241:

https://sourceforge.net/tracker/?func=detail&aid=407434&group_id=5470&atid=305470

There are still issues to resolve; I have to figure the right place to
convert the keyword and platform options from strings to lists, and
implement checking on the license option.

A sample package containing a PKG-INFO file is at
http://www.amk.ca/files/python/Distutils-1.0.2pre.tar.gz, should you
want to test some code on it.
