Customizable Engines and Drivetrains 1.4.1

Changes in 1.0
Added Customizable differentials to the cars that needed it. Covet and New pessima differentials is not included, because they are allready in my good friend @Djplopper 's Configurations modpack.
Changes to the turbos, they are now able to run more boost and act more like modern turbos, full boost kicks in harder and at rpm variable 2 instead of rpm varible 3 (earlier max boost)
Squished more bugs and refined it even more.

Since this is the last planned update for this mod I want you to post suggestions to further updates in the discussion page for the mod. Keep in mind that this mod is only engine and driveline related, so customizable tires or suspensions will not be in this mod.
