Atm_esp8266_httpc_simple gets stuck if server keep-alives connection

[euphi]

The http client gets stuck till timeout if the server does not close the connection when the request has finished.
Most (?) server (at least my default nginx) keep-alive the connection to wait for other http requests.

I have no real experience with http, so I don't know if there is a easy way to disable keep-alive from clientside. My solution/workaround: Close the connection, if the answer from server looks "finished", e.g. it ends with "".

Add in line 90 of Atm_esp8266_httpc_simple.cpp:

      if (response_data.endsWith("</html>\r\n")) client.stop();
