control to piston engines that allows external scripts to control the turbo/supercharger boost programatically by setting this axis to values in the range [0:1]. It also adds a "turbo-lag" attribute (a time in seconds) to engines implementing turbocharger spooling delays. This isn't terribly well tested, but doesn't seem to have broken anything.
