Title: Add option to pass in Alerter config

In many cases the response messages may need to use custom markup, rather than the default template from the `blocks-alerter` module. Since the that module allows the template to be overridden, and there are other options that we may want to pass to it, we should replace the `prependMessagesTo` option with an option to pass an alerter config object to `blocks-subscribe-email` like this;

```
var mySubscribe = new SubscribeEmail({
element: '#subscribe-form',
service: 'universe',
key: config.key,
alerter: {
prependTo: '#header',
template: customTemplate
}
});
```
