WaitCondition FnGetAtt broken

[Steven Hardy]

WaitCondition FnGetAtt("Data") always returns "None", whereas it should return the data associated with each WaitHandle signal:

http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-waitcondition.html

Need to fix this and add some tests.
