Use icc profile in OutputIntents

I wasn't able to get GfxICCBasedColorSpace::getRGB running with lcms if the icc
profile in OutputIntents is a CMYK connector, neither with
cmsCreateMultiprofileTransform() nor with cmsCreateProofingTransform(): I
always got wrong RGB colors back. But I'm neither a CMM nor a lcms specialist.
So I give up, but to get it running I now use the transform to get the correct
cmyk values and then convert it to RGB with the poppler utils. So with this
patch it is no more necessary to compile poppler with SPLASH_CMYK.
And, much more important: You'll see now the effects also in okular (and it
should be working also with cairo, but that's untested).
