+ response, like "FOO FOO=bar".
+ - Various address book database backend modifications. Fixed invalid
+ error checks in insert() and delete() methods (checks caused PHP
+ warnings). Turned on Pear DB field case portability mode. Escaped SQL
+ wildcards in search() method. Handle nickname changes in modify()
+ method when new nickname is already in use. Made search expressions
+ case insensitive in search() method.
+ - Added special folder (Drafts, Sent, Trash) translations in mailbox
+ tree and folder selection boxes.
+ - Added write support to address book LDAP backend. Patch by David

+ should be converted to html line breaks.
+ - Add note to conf.pl / config_default.php to warn users that set
+ sensitive passwords in that file to properly secure it.
