Title: AMQP-207

removed explicit mentioning of default exchange if key is not provided.
However, considering that no-key is still a valid optioin and would result in binding to the default exchange
we may want to consider making 'key' a required field on the directExchange binding while also stating that
if you want the default binding than you shoudl not have defined in the first place.
