filter for friends notification

[mpa4hu]

mensions notification has a filter which provides handy variables.

but `friends_format_notifications` does not.
I think it will be good for function to provide `$item_id` and `$format`

In 8169:

Friends: Pass $item_id as an argument for notification format filters.

Props mpa4hu

See #5314

mpa4hu - I've added the $item_id as an argument for the notification filters.

As for $format, I don't think that variable is necessary.

You can do a check for the format by checking if the notification is an array. If it is an array, then the format is 'array'. If not, then the format is 'string'.

Leaving it open for feedback.

I have not thought about checking array, thanks that works just fine!

Thanks for confirming. Closing this one!
