Add option to configure and publish RemoteAuxPort (event port)

[mrotteveel]

It's currently not possible to use events with this action. Could you add an option which configures RemoteAuxPort in firebird.conf and publishes that port if the option is set?

It looks like a very interesting feature.
I'll take a look as soon as I get some spare time.
