Color proofing support with lcms (http://www.littlecms.com/).

Enable with WITH_LCMS (options have been added for scons).
lcms is very common on linux package managers, so no need to add in extern (IMHO). Libs for windows can be added to /lib

Code is mostly a proof of concept with hardcoded path for icc profile (taken from the lcms test suite).

Adding this now to svn so it doesn't rot on my hard drive. People interested in pushing it forward should feel free to dig in the code or poke me about it.
