Problems with png files and libpng 1.6.3

[Benjamin]

[PATCH] Correct png colour profiles

In libpng 1.6, there are new warning messages which are output when the
image doesn't have a valid colour profile. The colour profile has been
removed using the convert tool in the ImageMagick package, with the -strip
argument.

The patch looks large because it contains the modified png files. There was
no code touched for this.
