[Peter Bloomfield <peterb src gnome org>]

    compose window: Chack BalsaSendmsg:ident
    
    BalsaSendmsg:ident may be destroyed while the compose window
    is open, and the only way we can know is if it is removed from
    BalsaApplication:indenties.
    
    * src/sendmsg-window.c (balsa_sendmsg_destroy_handler): check if
      BalsaSendmsg:ident can be found in BalsaApplication:indenties.
