foomatic-db-nonfree (cups ppd files): init at unstable/2015-06-05

`foomatic-db-nonfree` contains -- similar to its sister
package `foomatic-db` -- knowledge about printers,
drivers, and driver options from OpenPrinting in xml files.
It needs to be combined with the `foomatic-db`
package to yield a working database.
It also provides about 100 (gzipped) ppd files.
In contrast to `foomatic-db`, this package contains
data that is provided under non-free licenses.

ppd files can be found in
`$out/share/cups/model/foomatic-db-nonfree`.
The subdirectory `foomatic-db-nofree` is used to avoid conflicts
with other packages that might be combined with the package
`foomatic-db-nonfree` in `config.services.printing.drivers`.

ppd files in this package are *not* patched
to call executables from the nix store:
The only executable "rastertophaser6100" that is
called from ppd files isn't available in nixpkgs.

There is a daily snapshot of a source archive available at
https://www.openprinting.org/download/foomatic/ .
However, these files rotate daily and
cannot be used as a stable download source.
So we rely on OpenPrinting's Github repository
instead and pinpoint a fresh commit.
Note that the current version is from 2015,
so updates are unlikely.
