- Queue library fully renamed to ArduinoQueue (#11) - thanks @Defensor7
- Fixes chime not being heard on first button press after boot (#13)
- Fixes volume setting not being retained when device is restarted
Note that the fix for #13 involves (re)setting the volume on boot, which means that the chime will now be played on boot. This implicitly fixes the (unreported) issue where the volume was resetting to the default on boot, which may not be the volume you'd set.
