Enhancement of status page

[HuffYk]

I did a fork with small changes (mainly to status page):

• added check for ESP8266 or ESP32 and show it with pragma message (ends with pragma error otherwise)
• refactored status_string fnc to use String class
• added new info to status page:
  • ESP32 chip model and rev
  • ESP32 chip cores
  • ESP32 chip temperature
  • CPU chip speed
  • Flash chip speed
  • Flash size
  • SDK version
  • Wifi SID
  • Wifi IP address

if interested these are two relevant commits (forgot to put it into one PR):

• https://github.com/VladimirHirner/esp-arduino-ebus/commit/bde52397c2e8d22402e999a1b1226a02b9ba44c7

Hello, could you please create a PR? Although this is broken now already, I'd like to have a uniform format for all the status variables:

lowercase_name_of_variable_with_underscores: value unit

Could you also please change that?
