winecfg.cpl: Add new control panel applet for winecfg

Ah, I see now. Well, that's what I'm ultimately hoping to do, although 
as mentioned before, working out issues with the likes of how to 
integrate an interface for application-versus-global settings for each 
applet will require a bit of thinking. In addition, I imagine splitting 
up/redesigning winecfg is something that may involve a bit of resistance 
from those already accustomed to its present manner of working. This 
patch is just the first part of a submission to create a basic control 
panel skeleton - as I said before, I am hoping to redesign parts of 
winecfg and shift those parts into their own control panel applets 
(which technically can be all part of this same .cpl file). For the bits 
that don't get moved into separate applets, I don't see why a general 
Wine Configuration icon would be a bad thing, for the time being at least.
