Function send_to_keys_openpgp 

pub(crate) fn send_to_keys_openpgp(qt: &CxxQtThread<Sioul>, ident: &str)

“Send it to keys.openpgp.org”, pressed after the sentence that says what goes public: the certificate Sioul keeps for the key, its public part only, sent; keys.openpgp.org then mails each address it names a link. A demo profile sends nothing, and says what would come.
