Server application settings event

Add event emitter to the server to allow ultimate changes to application settings; useful for testing purposes.

The problem with the event approach as an alternative to a hook is that it will break as soon as you implement an asynchronous handler. I.e. it will not wait until the the handler alters the settings for creating the application.

Agreed. I went through with events mostly because it was a fastly reachable result. I think this can be easily modified to a hook, I try and have a look at that later.
