Make inner layers visible in footprints (lp:#1824621)
Original report created by eelik (eelik)
Inner layers aren't officially supported in footprints at the moment, but
they seem to be recognized at least by zones, routing and gerber
generating. The layer of a pad can be changed with a text editor. However,
inner layer pad's aren't visible in pcbnew or the footprint editor.
So, make them visible.
