Subject: [PATCH] fix README.md code bug and Change map to gin.H (#1963)

``` go
func main() {
        r := gin.Default()

        // r.GET("/JSONP?callback=x", func(c *gin.Context) { // old
        r.GET("/JSONP", func(c *gin.Context) {    // new
                data := gin.H{
                        "foo": "bar",
                }

                //callback is x
                // Will output  :   x({\"foo\":\"bar\"})
                c.JSONP(http.StatusOK, data)
        })

        // Listen and serve on 0.0.0.0:8080
        r.Run(":8080")
}

// client
// curl http://127.0.0.1:8080/JSONP?callback=x

// old output
// 404 page not found

// new output
// x({"foo":"bar"})

```

Most of the sample code in the documentation map[string]interface{} is represented by gin.H.
gin.H is a very important place for me to like gin, can write a lot less code
