Change Log:
2013-04-28 V1.1 - Fixed float error in loop timing, set TEST_MODE to 3.5 seconds
2013-04-27 V1.0 - Added comments, cleaned up debug messages.
2013-04-26 V0.5 - Added debounce to reset line
2013-04-24 V0.4 - Reset hold for 10s does a "test lights" mode, Easter Egg put in
2013-04-24 V0.3 - Button Lights and Sounds added, auto reset after RESET_TIMEOUT_SECONDS
2013-04-23 V0.2 - Button detect with ordering & LED light blinking logic finished
2013-04-18 V0.1 - Initial Version
Notes:
2013-04-24 - All functions working; ready for cleanup
2013-04-22 - Started adapting for full 4 button support
2013-04-18 - To drive 4 additional LED lights on the control panel, will have to use Analog IN for _BUTTON
