Gin [proposal] save the return line

Description

gin should do something to save the return line

How to reproduce

when met an error we use to lines to deal with it

    var err error 
    if err != nil{
        c.Status(http.StatusInternalServerError)
        return
    }

It will be cool to use return c.Status(http.StatusInternalServerError) or provide some alike method to support this

Please review

Added error return for c.Status(code) so that this can be used as return c.Status(code) to avoid/save extra return statement
