    foodgroups: eliminate add_to_groups() and struct fg_groups
    
    Instead use next_connection_new2old(kind=CK_GROUP) to find groups
    (note that it isn't accelerated).
    
    Also move the recursive call to delete_connection_group_instances(),
    nee delete_group(), in discard_connection() to delete_connection().
    One less way that discard_connection() can go recursive.
