fix GPG CertificateImpl::getSHA1Thumbprint not returning a
sequence of bytes as the thumbprint. (that is what the
documented API states, and what all of the code assumed.)
now /org.openoffice.UserProfile/Data/signingkey and
encryptionkey stores the key's SHA1Thumbprint for better
identification of keys. Previously on the key name was being
used.
fix annoying NSS Certificate Database password prompt
appearing on Tools->Options if the certificate database is
password protected.
improve Tools->Options->UserData user key selection and
display of information.
add a ui test for "Sign with default certificate"
interaction in the save dialog.
