Jetway SDK 1.3 Correction

If you have downloaded the V1.3 of the Jetway SDK and you are using gmax to build the model, please re-download the SDK, because it contained the wrong script files. This is now corrected and included in the SDK package and the wheels should now be animated.

[EDIT] July 6, 2016: I have fixed another issue with the stair angle calculation. Please recompile your jetway model with the latest scripts.
