Label internal projects

[cornelius]

We have a couple of small projects in the OpenRail GitHub organization which are not railway specific software but tools for managing the organization and its projects. These projects are out of the scope of the incubation process. We should mark them accordingly, e.g. with a GitHub label and document this somewhere.
