Expressive 1.0.0rc7

Added

• #277 adds a new class, Zend\Expressive\ErrorMiddlewarePipe. It composes a Zend\Stratigility\MiddlewarePipe, but implements the error middleware signature via its own __invoke() method.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #277 updates the MarshalMiddlewareTrait to create and return an ErrorMiddlewarePipe when the $forError argument provided indicates error middleware is expected. This fix allows defining arrays of error middleware via configuration.
