Experimental Plone 2.5 beta 2 installer with Zope 2.9

Hi all.

(Update: Please use the nightly builds instead.)

I’ve fixed the last one or two serious issues and have now a working installer for Plone 2.5 beta 2 using Zope 2.9 (except the installer still says beta 1).

If the brave folks running Windows out there can give it a try and report back any issues, I would appreciate a lot.
