[Distutils] Release of bdist_msi 1.0

["Martin v. Löwis"]

I just completed bdist_msi, based on feedback I received.
The files are available from

http://www.dcl.hpi.uni-potsdam.de/home/loewis/bdist_msi/

Here are the changes from the beta:
- changed ProductName to "Python x.y PACKAGE-a.b", to
  follow bdist_wininst, and to have the packages sort
  together in Add-Remove-Programs.
- fixed missing import
- added support for --install-script; dropped/disabled
  support for --pre-install-script (one implementation
  attempt is still there; if you manage to get it work,
  please let me know)

I plan to contribute this to Python soon, for inclusion
in 2.5.

Regards,
Martin
