KGlobalSettings cleanup

[Matthew Woehlke]

Ok, I'm not familiar with kdm, but does it *need* to be using the 
two-arg version of createApplicationPalette? The problem is that the 
code I currently have in kgs ignores both parameters. I can fix ignoring 
the contrast, but we need to re-think how colors are stored (and I think 
change KColorScheme) if the group must be honored. I would therefore 
prefer removing this entirely (kdm is the only user of the two-arg 
version AFAICS from lxr).

Also, can we kill calculateAlternateBackgroundColor? IIRC it has few 
users, and those probably can (and /should/) be replaced with using the 
appropriate alternate background color from KColorScheme (as in the 
@deprecated note). Otherwise KColorScheme::shade, or possibly 
KColorUtils::mix, is probably an appropriate replacement.

I would plan to make these changes next Monday if that's OK with the 
release team (I'm not clear yet if the 25th is before or after the hard 
freeze :-) ).
