Title: Configurable quotes

The transformers currently return both single (addDisplayName and quoteAttrName) and double quotes (JSON.stringify) in the transformed result, so it is impossible to enforce quote rules. I've added an option called useSingleQuotes that decides if double or single quotes should be used throughout.
