Subject: [PATCH 2/4] Allow "chicken-status -list" to be used with egg name
 arguments

This allows `chicken-status -list NAME ...` to generate output for just
the named eggs (or the eggs specified by a pattern with "-match"), like
we do with "-c" and "-f".

The default behaviour, listing all installed eggs, remains the same when
no name arguments are given.
