Releases app: Allow adding additional software
@bryceharrington asked on the Inkscape chat if it was possible to add lib2geom to the downloads served via CDN in the releases app (https://chat.inkscape.org/channel/general?msg=ztKxfBNE7e2CeAfpG). Currently, the app doesn't support any other downloads than Inkscape.
In the longer term, it would be useful if it were able to also offer other downloads via the versioned interface.
If that's not possible, Bryce could create a gallery for those releases, so they will at least profit from the CDN.
