filename used by shelve

[Nemesis]

Mentre io pensavo ad una intro simpatica "Fredrik Lundh" scriveva:

Hmm, this is a good idea. Thanks.

Anyway I think that shelve should provide a method which returns the
files used by the backend database, and the argument "filename" can
confuse users, it should be named "dbname".
