Plus character + is not properly quoted

[EllieTheYeen]

I sent a request that contained a plus + character in the body and noticed that it gets replaced by a space. As you might know many web servers do this therefore the character should be quoted to %2B by unirest or data will be malformed unless you compensate for this. This is for all urlencoded data both in the query string and url encoded post body. Urllib does not have this problem in functions such as quote or urlencode
