Filtering using bp_messages_single_new_message_notification

[henrywright]

bp_activity_single_at_mentions_notification allows me to pass $item_id and $secondary_item_id to my filter function where as bp_messages_single_new_message_notification doesn't.

Please see attached patch. Would this be possible? It would help as I need to use $secondary_item_id in my filter function to display the messaged member's avatar.
