There was no particularly good reason - in fact I started writing the patch to 
allow their specification in the .kcfg, but then discovered the relatively 
new IncludeFiles statement in the .kcfgc, and patched it instead. It doesn't 
really seem necessary to be able to specify includes in both files, and I 
agree that on balance it is probably cleaner to have them only in the .kcfg.
