Don't serialize MVC return nil

[lightglitch]

func (c *Controller) Get() *iris.Map {
return nil
}

Should be a way to not serialize nil as null, because sometimes we don't want to write anything to the output.

A note:

@liguoqinjim you don't have to use * pointer in iris.Map it's just a map[string]interface{}.

I understand, however, it should be optional so I will introduce an optional mvc/hero configuration for the upcoming v11.2.0 which you will be able pass to declare "rules", it will be useful for any future request as well, sounds good?

UPDATE: Oh, that's a bug, the response shouldn't be send as "null" if the *iris.Map itself is nil, fixing it as we speak!
