New option "labelPosition" on axis to control if label is left or right on secondary axis

[beberlei]

The idea is that on the secondary axis the label should not be on the left (default), because that lets it get rendered into the chart. With its position being right, the label is outside of the charts values:

        $chart = new ezcGraphLineChart();
        $chart->palette = new ezcGraphPaletteBlack();
        $chart->xAxis->axisLabelRenderer = new ezcGraphAxisExactLabelRenderer();
        $chart->xAxis->labelPosition = ezcGraph::RIGHT;

The option is a bit misleading right now, because it needs to be combined with $axis->position which it interacts with.

Yes, it doesnt work with all cases, just my special case for now.
