WiFi connection now occurs asynchronously so that if WiFi is lost, or cannot be connected at start-up, the device still operates intead of blocking while it tries to connect. The new logic should allow for a wider range of chips to connect.
This change allows the user to set the log-level with homeSpan.setLogLevel() instead of needing to change in Settings.h. Next up: Update Example that introduces VERBOSE to instead use setLogLevel(). Consider adding an interactive 'L' command to change this during run-time.
Also, added "#pragma once" to every *.h file to prevent duplication of definitions. TO DO: Review all #include to ensure sanity across all files.
Created separate init() methods for PushButton and Blinker. Created HomeSpan:setControlPin and HomeSpan:setStatusPin that can be called from main setup() to modify the defaults. All default settings being migrated to Settings.h
Allows for reset of HAP (press for 5 seconds, but less than 10) or Factory reset (press for 10 second). Use setResetPin to change from default of pint 21.
