Support for 24 hour time format

[Sopwafel]

I stumbled upon this problem too, but I McGyvered a solution:

myTimeAxis.axisConfigurations().forEach(tierConfiguration =>  
      tierConfiguration.forEach(function (row) {
        if(row.interval === "hour" || row.interval === "minute")  
          row.formatter = new Plottable.Formatters.time("%H:%M")  
      })  
 )  

With myTimeAxis being a Plottable.Axes.Time object.
I used http://plottablejs.org/tutorials/time-axes/ and https://github.com/d3/d3-time-format/blob/v2.2.3/README.md#isoFormat.
