Remove cviewd from super-repository

cviewd was never packaged for Debian and hence does not need to be
included into the super-repository
Move debathena-common to the appropriate path
Remove debathena-libss and debathena-libreadline

Those are equivs packages on which nothing in the super-repository
build-depends anymore.
Remove cluster-cups-config

It is supreseded by cupsys-config and was not even built for precise.
Remove finger-config and fingerd-config

The only supported distributions for which these were built are
lucid and squeeze.  Even though those are not gone yet, the chance
of it being rebuilt is extremely low, hence they are removed from the
super-repository.
Remove debathena-command-not-found

This appears to be something that was never built, and is probably
something that should never end up in the repo anyways.
