You can subscribe to **all** shower events.

```js
shower.on("test", function() { alert ("test event"); });
shower.on("all", function(name) { alert(name); });
shower.trigger("test");
shower.trigger("foobar");
```

So, this code fires these alerts:

1. "test event"
2. "test"
3. "foobar"

Does it make sense?
