Subject: [PATCH] Add "-colorspace rgb" to our ImageMagick calls

The old PNGs that were generated caused a warning from libpng when they were
read:

    incorrect gamma=(0/100000)
    Ignoring incorrect gAMA value when sRGB is also present

This changes the look of the resulting icons by making them darker. However,
right now I just want to get rid of that stupid warning. Feel free to suggest
better options.
