Website at invenio-software.org should redirect

A Google search for Invenio leads to invenio-software.org. That domain has non-working HTTPS (though Google links to HTTPS), and seems to be built from this repository but from May (lagging waaay behind).

[Wikipedia also links](https://en.wikipedia.org/wiki/Invenio) to invenio-software.org.

You should try and update those links:
* via Google's webmaster tools
* editing the Wikipedia article if the domain has changed
* make invenio-software.org redirect, if you still control it
* add a `rel=canonical` to invenio-sotware.org
* probably add a disclaimer to this repository about the existence of that other domain, because it took me a while to figure out why changes here weren't reflected on invenio-software.org

No repository file, test, or entry point is named. Start by reviewing the website source and the current invenio-software.org behavior, then check the Google and Wikipedia references; done means the outdated-domain handling and any repository disclaimer or link updates are clearly resolved.
