* Pass client parameter into two new begin() functions. Set other begin() functions deprecated. Updated library version to 1.2
* Added working HTTPS example on a public url with a certificate
* Remove two unnecessary tests in ::disconnect()
* Add a scoping block to BasicHttpsClient.ino to assure HTTPClient is destroyed before WiFiClientSecure
* Added check to handle mixup of old and present api properly
* Correct HTTPClient::setTimeout() to convert milliseconds to seconds. Correct WiFiClient::setTimeout() to call Stream::setTimeout() with seconds converted back to milliseconds. Remove inproper checks for _insecure.
