Add documentation for custom service events

[daffl]

#128 adds the functionality but the documentation has to be updated (now in the main repository because of #127).

This probably still needs to be added to the docs.

It does indeed. I didn't get the service.filter functionality into 1.1 though so custom events are not too useful since they get dispatched to all clients without a way to filter it.

I've set up a placeholder for this here: https://github.com/feathersjs/feathers-docs/blob/master/05_events.md#custom-events

This has been added at http://docs.feathersjs.com/clients/readme.html#custom-events

I think the service setup stuff belongs on the events page. But we would want to still show how the client can listen to custom service events on the clients page where you have it now. Something like:

If you're using custom events you can listen to them on the client like this...

Does it support add custom event at runtime?

[daffl]

You can add services at runtime (that can have custom events) but not new events to an already registered service.

Is there a way to support add events after service has been registered? Otherwise, is it support to unregister and register the service again when adding new events
