Title: signal 'I have a broadcast function'

This allows elements to say whether or not the are broadcasting at all in their definition, using:
```

```

This gives all element instantiations a `.broadcast` function property. If present, this element can broadcast (note: *can*, not *does*, which requires that the broadcast function actually calls `this.emit`) and the element will be built with a default broadcast channel. Elements lacking the `.broadcast` function property will have a broadcast channel "false" (`Ceci._emptyChannel`)
