Route the wiimote speaker to the sound mixer (the host system's speakers). Emulated Wiimote speaker sounds will go to the host system's speakers. Real Wiimotes will continue to use their own speaker for Wiimote speaker sounds. All Wiimote speaker sound can be disabled by unchecking the "Enable Speaker Data" option.

Each emulated Wiimote can have its speaker routed from left to right via the "Speaker Pan" setting in the emulated wiimote settings dialog.  Use any value from -127 for leftmost to 127 for rightmost with 0 being the centre.

Added code in the InputConfig to use a spin control for non-boolean values.

Defaulted the setting of "Enable Speaker Data" to disabled.
