As Signal Desktop does not allow its users to update the contact names, it would be nice to be able to update contact names from signal-cli when the latter is the master device. The command `setContactName` allow to set the name for the given contact in the local store. `sendContacts` can then be used to push the updated contact list on Signal servers. Closes #228
