Tooltip formatting options don't work for scatter chart

[pawelfus]

For other types it works fine, but for scatter doesn't respect headerFormat and pointFormat: http://jsfiddle.net/Fusher/Sq3KL/1/

The problem is that scatter has its own pointFormat and headerFormat defined in plotOptions.scatter.tooltip. So we need to override this: http://jsfiddle.net/highcharts/Sq3KL/2/.

We need to find a smarter way to check whether the tooltip option has been altered.

The same applies for an arearange chart: http://jsfiddle.net/M6PLJ/7/

... and for columnrange

So will this bug be fixed?

Proposed solution: In Series.js, in the setOptions method, set the series.tooltipOptions like so:

        // the tooltip options are merged between global and series specific options
        this.tooltipOptions = merge(
            defaultOptions.tooltip,
            typeOptions.tooltip,
            chartOptions.tooltip,
            plotOptions.series && plotOptions.series.tooltip,
            itemOptions.tooltip
        );

It still feels like a bloat, since we're doing similar things with options in general...
