Generic Development 1

[dmadison]

A few miscellaneous updates:

• Adds a Simultaneous Opposite Cardinal Directions (SOCD) cleaner, to prevent the directional pad from outputting opposite directions simultaneously (required for fighting games). This can be avoided by using the setDpad function with only one input at a time.
• Adds releaseAll and reset functions to clear all inputs and set the class to its initial values.
• Treat joystick ID enums (JOY_LEFT and JOY_RIGHT) as buttons "L3" and "R3" when passed to the button functions.
• Adds automatic input scaling for trigger and joystick values. User can set the input range and the values will be automatically scaled to the range of the outputs.
