Change OpenPGP key defaults to match GnuPG's
This causes kleopatra to generate OpenPGP keys
with a Sign / Certify primary key and an Encryption
only subkey.
The advanced options still give you the option to
generate a SCE Primary key without subkeys.
This change has been requested by the GnuPG maintainer
and was discussed on the Gpg4win-devel mailing list:
