bbdb enhancements?

[dieter]

I think it would be nice if the email-field(s) have labels
like the phones (and addresses). Maybe with 'work' and 'home' as defaults?

With something like that the bbdb-vcard-export could be made "more khard
compatible".

And maybe the uid could be made more "more khard compatible" too? For
"better" creating vcf-file names. And export the uid into the vcard as
'UID' too?
The khard program could read the uids of bbdb (if the file name is an
uid) but it creates uids without an '-'.
