Examples Rework

[dmadison]

This PR combines both the ESP8266 and ESP32 examples into one, as they were near identical other than the WiFi include statements and the setInsecure() function call on the 8266 version. Both of these are now handled with preprocessor statements.

While I was at it I also made a few other improvements:

• Standardized whitespace (tabs for indentation)
• Fixed the millis overflow issue with the request limiter
• Adjusted comment language and formatting
• Improved code and serial output readability
• Disabled additional debugging by default

Other than the millis fix there should be no functional changes to the example itself for either board.
