Working on manual.

Added code for `--gpg-key-id' option for `gwirdsif'.  This is now required.  Added code
for using GPG public keys for users.  This is currently only needed for the function
|Scan_Parse_Parameter_Type::send_tan_list|, however, this feature is non-functional at present and
I don't know whether it will be needed.  GPG keys for users, however, may be needed for other purposes.

Added the subdirectory `gpg_keys' with public and secret keys for "dummy" users.
