Fail: Configuration parameter 'falcon-env' was not found in

The Blueprint configuration processor is not correctly handling the case of a
component, such as Falcon, that includes "excluded" config references in its
stack definition. This appears to be a regression.
I'm working on a patch to resolve this, and will be submitting it shortly.
