Removing support for lcms1

[Boudewijn Rempt]

Hi,

This weekend we figured out that a primary reason for instability in Krita is lcms1. See for instance https://bugs.kde.org/show_bug.cgi?id=285552. Lcms2 is both faster and safer in a multi-threaded environment. I had wanted to keep lcms1 support for 2.4, but I think this is no longer tenable.

The biggest problem is Windows, where kde-windows doesn't have lcms2 support yet. I hope to fix that tonight. All current Linux distributions package lcms2.
