Preparing fabric for publishing through npm. Make fabric.createCanvasForNode accept width/height rather than reference to node-canvas, to prevent user from having to instantiate node-canvas instance. Add fabric.Canvas.prototype.createPNGStream which is a simple proxy for node-canvas createPNGStream.
