aggregate-error-ponyfill

ES Proposal spec-compliant ponyfill for AggregateError.
The AggregateError object represents an error when several errors need to be wrapped in a single error. It is thrown when multiple errors need to be reported by an operation, for example by Promise.any(), when all promises passed to it reject.
