Outdated ETK 800 *Sedan-Fastback-Coupe-Cabrio* 2.3

Hotfix for 0.9.x including:

• new screen setup (thanks to @FLyInG 2 YoUr SoUL for mentioning the code in the discussion, didn't had to search myself )
• changed suspension mounts for new front suspension setup (thanks to @Firepower for letting me now what has to be changed)
• dirty hotfix for stress in coupe and convertible tailgates/trunks (removed some coltirs, might result in clipping of those parts in crashes)
