Merge pull request #63 from krishnakumarp/master

Fix for issue #62
Added code to allow more than one param with the same key.
AsyncHttpRequest now knows if the host is unknown (down or internet down)
Further verification on the JSon format of the response Handler.
Added POST method that takes an entity and amended comments.

I've added a method that will take an HttpEntity
along with an array of Headers. It looks like the
version that now takes a RequestParams object
originally did this as the comment-block for it
still referred to HttpEntity so I've amended that
(and appropriately commented the new method).

Fix NullPointerException in JsonHttpResponseHandler

If result is null after new JSONTokener(result) which means response is
not a json type, assign result to responseBody to avoid makeing
NullPointerException and also makes handleSuccessJsonMessage able to
create a JSONException with right jsonResponse's class name.
