NOW documentation users are sent to CORE doc module pages because we don't want to duplicate content from CORE in NOW.
At least tag the module pages with the label mnow.

Not sure whether we need a "badge"/info box, cloudy icon, etc. pp on the CORE pages.
We have to wonder how obvious it should be for the readers of the CORE doc which modules are available on NOW and which not.
For me (cmeier) this is rather a technical labelling to be reused on the NOW docs.

Test generating a list of tagged CORE content in NOW docu space.
