The ability to select 1 or more or all the pgp entries and import them into the
address book with 1 click.
The email address would be taken from the email field of the pgp name, the
comment part of the pgp key would go into the notes/comments section of the
address card, and the name field of the pgp key would go into the displayed-as
field of the address card. If it has 3 names in the name field of the pgp key,
it will be split into 3 parts, the first word going into the firstname
addrescard field, the last word going into the lastname addresscard field, and
any names in the middle being assigned to a middlename address card field.
these addresses would be imported not into the regular address book, but into a
special "Enigmail Addresses" book (which could be specified in preferences but
thats not necessary).
