Fixed bug 2025 - Update 1.2 OSX Joystick code to fully support Saitek p2500 gamepad

Patrick Maloney

Saitek p2500 (Cyborg Rumble Force Pad) has a D-pad, two analog sticks, and numerous buttons.  SDL 2.x on OSX detected everything except the right-side analog stick.  The right-side stick is considered a 'simulation device' with the axes mapped to throttle and rudder.

The patch adds support for throttle and rudder on the HID simulation page.
