A few patches to apply against Sylpheed and Sylpheed claws sources.

Adds LDAP servers/search to addressbook. (requires sylpheed-claws 0.4.99)

Very very simple patch that adds CC in the list of symbols (from the common prefs) allowing to include CC field in replies quotation formats or forwards formats.

Nb. Theses patches have been removed from here as the first one has not been retained in sylpheed/sylpheed-claws (addressbook has completely been rewritten) and the second one has been incorporated in 0.5.1
