- Raised limit of 2 axis to 4 axis pairs (4==8 joysticks axis pairs) - Added a new Joystick Sensor type "Single Axis", so you can detect horizontal or vertical movement, rather then just Up/Down/Left/Right - added Python attribute "axisSingle" so you can get the value from the selected axis (rather then getting it out of the axis list) - renamed Py attribute "axisPosition" to "axisValues" (was never in a release) If we need to increase the axis limit again just change JOYAXIS_MAX and the button limits.
