Title: simplify upgrade steps

from the changelog:

API CHANGE: Restructure and simplify upgrade steps and create dedicated plone3
integration profile. If you want to install this package in Plone 3, please
use the plone3 profile.

the simplification was done more out of simplification mood then necessity. but why not having a simpler upgrade step story and leaner integration code base?
