Travis CI and beyond?

@icemac created a tool to update CI and more for Zope repositories, maybe this could be adapted for Plone, too

I think some of the ideas and the configuration could be used. But the rest might be too zopefoundation specific. We tried to use it for our gocept open source repositories and failed because they are too different.
