Title: Unbound local error in get_dynamodb_type when using set types. 

I am not 100% sure how this should work. It would appear DynamoDB only supports set types as long as they contain either ONLY strings or ONLY numbers. So this change supports that logic. If it works some other way, it should be reflected in the source here. I ran into this issue while implementing sets for pynamo: https://github.com/samuraisam/pynamo
