title: Disable pinch to zoom in highstock/highcharts
body: <p>With the new update for highcharts came support for pinch to zoom on the iPad/iPhone, however this doesn't work how I expected.  I presumed that the chart would actually zoom into the date range, instead it just literally zooms into the chart lines and markers, rendering the functionality a bit pointless.</p>
  
  <p>Is it possible to disable this?</p>
