[PATCH] emacs: functions to import sender or recipient into BBDB

[Daniel Bergey <bergey@alum.mit.edu>]

From a show buffer, bbdb/notmuch-snarf-from imports the sender into
bbdb.  bbdb/notmuch-snarf-to attempts to import all recipients.  BBDB
displays a buffer with each contact; C-g displays the next contact, or
returns to the notmuch-show buffer.

Both functions assume that email contacts are seperated by commas.  If a
comma is included in a name, it will try to make two separate
contacts.

This is my first notmuch patch.  Comments very welcome.
