Support font color

Thanks for this nice UI. Could you support props.fontColor as the font.fillStyle? It would look nice if font and circle use different color.

Would also really like this change. Not that familiar with coffeescript, but it looks like it should be here: https://github.com/pughpugh/react-countdown-clock/blob/master/coffee/react-countdown-clock.coffee#L168

You could take another parameter called fontColor then use it to set fillStyle here, draw the text, then use the color parameter to set fillStyle again before drawing the arc.
