* gpgkeys_ldap.c (delete_one_attr): New function to replace attributes

Browse Source 
with NULL (a "delete" that works even for nonexistant attributes).
(send_key): Use it here to remove attributes so a modify operation starts
with a clean playing field.  Bias sends to modify before add, since (I
suspect) people update their existing keys more often than they make and
send new keys to the server.
