Use CUPS by default

[geofft]

We're currently defaulting users to LPRng /etc/debathena-printing.conf; we should switch back to CUPS at some point when we've resolved the client-side issues that are making us want to default to LPRng. This is somewhat orthogonal to resolving all server-side issues and figuring out what the campus IPP printing mechanism will be.

If possible, we should also avoid removing /etc/debathena-printing.conf if it had been created manually before the version of debathena-printing-config that includes it, but that may well be impossible.

The biggest reason to default to LPRng is that lpq and lprm just don't make sense if you default to CUPS, and I don't think that's going to change any time soon.

That's not possible. We're not diverting that file, just dropping it in, which means that when I added it, it would have scribbled over anybody's local configuration. This was definitely a bad decision on my part, but there's not really anything we can do about it at this point.

With the new logic in printing-config, we basically are using CUPS by default whenever that's possible.
