[csw-maintainers] Tiers

[Peter Bonivart]

I suggest that we agree on the core packages, there shouldn't be too
many of those, especially on the top level (not counting the
dependencies that are dragged in). Active we could see what packages
have been updated within a reasonable time (a year?) or has a
maintainer that updates other packages (not all packages need
updates). The rest are unmaintained.
