Further weight saving

[david]

the weitgh difference of a standard bonnet and a carbon on in really peanuts, saw 2 models at TMS and checked them, it's not so light with the double structure and the trust bars to make them more solid and less flexible

for exemple le xenon package is 9kg more than the normal lights system

I think and by memory all the options on a Csl as: parkage assistance, aircon, radio, xenons are 36kg all removed
