KisAbstractColorSpace is now known as KisLcmsBaseColorSpace, and the 
idea is that not every colorspace will use that
KisColorSpace is now a virtual base of both lcmsbase and each of the U08 
type bases

So say rgb08 would inherit from both KisLcmsBaseColorSpace and 
KisU08BaseColorSpace

With diamond shaped inheritance final colorspaces (like rgb) has to call 
the constructor of KisColorSpace.

Also the conversion colorspace used as fallback is now Lab. meaning that 
_every_ colorspace _must_ implement to and from Lab function.
