Subject: [PATCH] Bug on setting extra headers. Now it loses the first string
 character. (#184)

Client code:

    ...

    ix::WebSocketHttpHeaders headers {
        {"Cookie", "ABC"}
    };

    ...

Expected header string on server:
    "Cookie: ABC"

Resulted header string on server:
    "Cookie: BC"

Solution:
    The easy way I found to solve the problem is to add a space where extra headers are set before sended to server.
