Re: split of mockup / plone.mockup

FYI: I just ran into a problem with the plone.mockup pkg:

ConfigurationError: ('Invalid value for', 'package', 'ImportError:
Module plone has no global mockup')

I just did a "git pull", "bin/buildout" and "bin/alltests" on an
existing and working buildout.coredev.

I had to do a "git submodule update" on the plone.mockup repo manually
to fix this.

Let's please remove that package until we find a better solution. We
can't just use buildout.coredev as a playground for new and untested stuff.

BTW: my main point was actually that nested and complex structures are a
bad idea in general, the CI problems are just a symptom of that.

Cheers,
Timo
