Subject: [PATCH] In the core's response.go, add an optional RedirectCodeSetter
 field or variadic use303 ...bool parameter to Redirect() and use the stored
 code + http.StatusSeeOther in core.go instead of the hardcoded
 http.StatusTemporaryRedirect, so that a POST handler can redirect to a GET
 route by calling c.Response.Redirect("/url", true).
