Updated to new API as discussed on the Arduino Developers mailing list. Part of the process of moving the library to live as one of the core Arduino libraries.

The get/put/post calls have been streamlined to require fewer parameters in the basic case - i.e. you can just call http.get("www.mysite.com", "/somepath") to make a simple request.

The accept header has been removed from the list of possible parameters to get/put/post - if you need to use it then send it manually with sendHeader(...) instead.

You don't need to call finishRequest() after the initial call to get/put/post if you aren't going to send any headers.  However, if you /do/ want to send extra headers then you need to call beginRequest() before the get/put/post and endRequest() at the end of all the sent data (so after the data as well as the headers).  E.g.

	http.beginRequest();
	http.post("www.somesite.com", "/somepath");
	http.sendHeader("Content-Length", strlen(postdata));
	http.print(postdata);
	http.endRequest();
