Implemented workaround for bug with qml property binding. Now the state of the checkbox will always match up with the state of the outputEnabled.

Joystick axes and buttons can now be monitored even when the
joystick input is disabled.

Made it so that raw axis monitor indicators are narrow so that they don't obscure view of the deadzones.

Changed Joystick._exponential from bool to float. It can now be set between 0 and -0.5 by user using a slider.
