Move all older folders from the foia repository into /archived

I've removed non FOIA modernization data related files and folders from what is now the foia-data repository (previously known as foia). These are now places in an archived folder for now. It doesn't seem like we've been using them all that much recently. When we do, we can find more sensible homes for these files. 

Also, this adds the standard contributing and license files to keep things consistent.
