Generalize pubkey checksum display and check and introduce `checksum` command

• #333 (closed): Always display a pubkey with its associated checksum
• Check checksum validity when a pubkey is passed
• Add new checksum command: you pass the pubkey and then it returns: <pubkey>:>checksum>
• #302 (closed): Checksum mandate when passing a pubkey

changed milestone to %0.9.0

added Authentication Feature Security labels

mentioned in issue #302 (closed)

changed title from Add ability to generete a pubkey’s checksum to Add ability to generate a pubkey’s checksum

changed the description

I guess the checksum should always bedisplayed.

Since this feature is a question of security, I suggest we add it to silkaj in a 0.8.X version so it would be included in the Debian package for the next 2 years. At least for the tx confirmation, since it is the case when most errors happen.
