Aerodynamic tweaks for R26

Renault showed up at Hockenheim with again an updated aerodynamic package. This time around the ears were again replaced by single element wings instead of the double element layout seen at Canada and Indianapolis. These simple items were also present at Magny-Cours. Secondly, a vertical fin was added on the upper front wishbone. It is exactly as far away from the nose as the width of the camera hose positioned just in front of the wishbone. The element is most likely to straighten vortices created by that camera.
