Updated notifier component.

This update to the notifier component allows multiple notifiers to be
configured. In order to support this, an optional property “name” has
been added to all the notifier’s configurations. The notifier can now
be called with the service “notify.NAME”. If the name is not provided,
the service will be mapped to “notify.notify”. Because of this, this
update should be fully backwards compatible.
