getFavouritesOfUser()

ilFavouritesDBRepository::getFavouritesOfUser	(	int	$user_id,
		?array	$a_types = null
	)

Get all desktop items of user and specified type.

note: the implementation of this method is not good style (directly reading tables object_data and object_reference), must be revised someday...
