Good idea. So one small js file with one var in plasmacomponents would already 
suffice, indeed. (I think it should be something globally accessible, not "per 
app" as this is especially useful for other components. I suppose we could 
reduce the delta of the touch-specific components and the general ones quite a 
bit.)

Other candidates for "global vars" which I often end up more or less 
hardcoding: 

- sensible iconsize
- margin (for example around text, one can always dynamically adjust it, but 
  having some globally adjustable knob would be nice)
- "standard" animation duration (though one can just load the .js file from 
	PlasmaExtras, like the animations in there do)
