Plone 5 specific code, not working in the 1.x branch for plone4.

This code looks like specific for plone 5.

https://github.com/collective/Products.windowZ/blob/master/Products/windowZ/profiles/default/metadata.xml

Removing the dependencies made it work in plone4, where Archetypes is already installed. One suggestion is to revert the commits with plone5-only-changes(things not needed for plone4).

Start with Products/windowZ/profiles/default/metadata.xml and compare its dependencies with what the Plone 4-compatible 1.x branch provides. Review the commits that introduced the Plone 5-only changes, then verify that the metadata works with Plone 4 and that removing or reverting only incompatible dependencies resolves the issue.
