Title: Feature/exclude nil values

On a current project we have the requirement to exclude all nil values from the JSON API. Although this is possible with the Attribute lambda we would like to be able to exclude nil values for all responses. I have added a configuration option - with the sensible default being not to exclude nils - to do this including tests.
