* SMIME: Crash if public certificates are located in an inaccessible
remote server and the private key is not available.
* SMIME: Management of several alternate name (SAN) certificates is
improved. When importing a SAN certificate, also import a certificate
for the filename, besides for the e-mail addresses in the
certificate.
* When saving an attachment, the "^T" command leads to a screen where the
"A" command can be used to add a file. A directory can be added by
pressing "^X" after the "A" command. Added after a suggestion by
Stefan Goessling.
