[*] Added a line break in the output of the error about not specifying the correct number of signatures for multi-signature.

[*] Fixed a bug that caused datum to not process with an unknown error if chane is not explicitly specified.

[*] Bug fix: Now for the global_db get_keys command, if no data is found in the specified group or the group is missing, an informational message will be displayed instead of an error.

[*] A nonce field has been added for token declaration and token update. Also processing of parmeters total_sign, datum_type_allowe, datum_type_blocked, tx_reciver_allowed, tx_reciver_blocked, tx_sender_allowed, tx_sender_blocked and creation of TSD sections now occurs during parsing of arguments, since this functionality should be available both for token declaration and updating.
