Optimize huffman trees, and make all jpegs progressive. #29

I don't know how hard this'd be or whether or not imagemagick allows you to optimize the huffman trees/make the images progressive but I do know that jpegtran allows that to happen on its own. Adding those options would also greatly help reduce the total space required.

Crap I can't edit it.

So here's the rest of it.

The optimization passes should add that at the final step once you've found the best quality level since it definitely helps reduce the total size.

OK, it's not a ton with the example images(in the after folder). It goes down by ~4%. Which isn't insane, but still the whole idea of this thing to is to make the images as small as possible without visual quality loss.

Thanks for the info, I will look into it.
