1.8.7: Bug fixin' for keyboard support

• Fixed keyboard-only support: no more crashes when no gamepads are present
• Fixed Keyboard input events when null controllers are present (when maintainPlayerPositions is set to true)

1.8.5: Better support for multiple devices

• Added an option to maintain the "player" seat based on controller id (maintainPlayerPositions)
• Added support for device detection via signals (onDevicesChanged) and device info getters (getNumDevices(), getDeviceAt(), and getDeviceTypeAt())
• Removed distinction between "sensitive" and normal controls; everything is a sensitive control

1.5.5: Stability and flexibility updates

• When a device is not recognized, just fail with a trace() message rather than crash
• Controllers data now use an array of strings for filters
• Added support for SELECT meta control

1.5.2: Automatic mapping of different gamepads to a common list of controls

• Added support for "split" controls, where the same GameInput control fires two distinct buttons (e.g. XBox 360 dpads on OUYA)
• Added support for PS4 controller (and OPTIONS, SHARE and TRACKPAD meta controls)
• Moved gamepad data to an external JSON (cleaner maintenance)
• Added ability to inject game controls from keyboard events (used for some meta keys on some platforms)
• Added gamepad index filter support for isActionActivated() and getActionValue()
• Removed max/min from addGamepadSensitiveActionBinding() (always use hardcoded values)
• Completely revamped the control scheme by using "auto" controls for cross-platform operation
