Wrong listen config path

[claudiu-cristea]

listen.pp is always trying to create the port listening file under in /etc/apache2/conf.d.

On Ubuntu Precise the config files are under /etc/apache2/conf-available and with symlink in /etc/apache2/conf-enabled

Maybe it would be possible to check if conf-enabled exists and then use the new ubuntu structure instead?

[alvagante]

Yes, definitively. PR welcomed.
