Lines are not the same as in AnimateCC, missing linecap and linejoin [fix]

[herrKlein]

When exporting line icons, the cap and the join are in the export from AnimateCC, but are not processed in the SnapSVGAnimator.

shape.attr({
  stroke: colStr,
  strokeWidth: resourcePath.strokeWidth,
  strokeLinejoin: resourcePath.strokeLinejoin,
  strokeLinecap: resourcePath.strokeLinecap
});

Adding these last 2 lines in the SnapSVGAnimator.js file on method this.addStroke = function (shape, resourcePath) { seem to fix that.
