On-the-fly GIF palette modifying

On-the-fly GIF palette modifying is done, and it's incredibly fast:

http://www.picpix.com/brad/pic/00033f2e

Let's change palette index 0 to green!
http://www.picpix.com/brad/pic/00033f2e/p000ff00

And palette index 1 to orange!
http://www.picpix.com/brad/pic/00033f2e/p000ff001ffc000

And palette index 3 to yellow!
http://www.picpix.com/brad/pic/00033f2e/p000ff001ffc0003ffff00

Best of all, we still get cache-control with all this... etags still work, etc.

And this concludes the palette swapping demonstration.

Now to start reviewing Mart's huge fricking "I'm back from the dead" S2 file.
