Hello,

when using a dedicated GNUPG_HOMEDIR for the keys of a party's
participants, it's convenient if gpgparticipants-filter emits all keys
when no filter is provided.

The following patch implements this feature:

Subject: [PATCH] gpgparticipants-filter: Make filter argument optional

Without arguments default to list all keys which matches the behavior
of `gpg --list-keys`.
