Allow empty certFile and keyFile for ListenTLS()

In order to use multiple TLS certificates that can be added/removed dynamically at runtime, without restarting the server, `config.Certificates` must be empty and `tls.Config.GetCertificate` must be implemented as documented [here](https://golang.org/pkg/crypto/tls/#Config).

This commit allows the user to leave the `Certificates` slice empty, so `tls.Config.GetCertificate` can be used.
