Glasses can now be set to any color you want. Only applies to the "Classic" style, though. Unless I find the other glasses in SVG format as well. As a nice side-effect, the glasses can now also be set as semi-transparent!

All thanks to some clever (mis)use of SVG and canvas, see https://github.com/klimeryk/dealwithit/commit/d8f280b5f2e4bd.... Enjoy!
