Having had a brief look into it, currently the control panel attempts to 
launch the appropriate .cpl file that would be launched on Windows. I think, 
rather than altering this to load winecfg instead, it'd probably be best to 
leave any changes here for the time being. If I do (or someone else does) 
end up splitting up winecfg, then the best plan would simply be to name the 
resulting control panels in a way compatible with Windows.
