200 OK response on NOOP command

[mibes]

At the moment go-guerrilla returns a 200 OK upon receiving a NOOP command. Our client expects a 250 OK. The latter seems to be in line with the RFC.

We fixed this by making the following code change in enhanced.go:

        Canned.SuccessNoopCmd = &Response{
		EnhancedCode: OtherOrUndefinedProtocolStatus,
		BasicCode:    250,
		Class:        ClassSuccess,
	}

If this does not break anything else, you may consider this change for an upcoming release.
