emacs: functions to import sender or recipient into BBDB

From a show buffer, notmuch-bbdb/snarf-from imports the sender into
bbdb.  notmuch-bbdb/snarf-to imports all recipients.  Newly imported
contacts are reported in the minibuffer / Messages buffer.

Both functions use the BBDB parser to recognize email address formats.
