Earle F. Philhower, III 0d15723444 Add HTTPClient, ported from the ESP8266 (#784)
Remove the need to have a separate WiFiClient that's destroyed after
the HTTPClient.  Let the object handle its own client, and pass through
any SSL requests.

Also supports the original ::begin methods which need a
WiFiClient(Secure) to be passed in and managed by the app.
