Title: Include custom attributes in emails & SNS notifications

Uses riemann.codec/event-keys for a list of default
attributes on an Event. Other keys on an Event are
custom attributes and are presented separately.

* Add riemann.common/attributes, returns a sub-map
of an Event including only custom attributes.
* Include custom Event attributes in riemann.common/body
* Used for email and SNS notifications
