    Add index on ObjectCustomFields.ObjectId
    
    Enhance performance of queries looking for custom fields by the specific
    objects that they are applied to, e.g. RT::Queue->TicketCustomFields to
    find the custom fields for tickets in a particular queue.
    
    Primarily benefits installations with a very large number of custom
    fields.
