TGEA 1.7.0 Beta 1 Bug - QuickFix for Flyingvehicle Engine sounds

As mEngineSound->play(); is not called during datablock assignment (to keep it from playing during load time, perhapse?)

the simplest methodology I can think of to put that back in without undoing the work is:

void FlyingVehicle::updateEngineSound(F32 level)
{
   if ( mEngineSound ) 
   {
	   if (!mEngineSound->isPlaying()) mEngineSound->play();
	   mEngineSound->setTransform(getTransform());
	   mEngineSound->setVelocity(getVelocity());
	   mEngineSound->setVolume( level );
   }
}
