Provides a single "defer()" function that returns an object that is both a
deferred and a thenable promise.  It supports multiple listeners.  It does
not support promise composition (since "then" returns nothing), forwarding
(since "resolve" does not accept further deferred promises), and it does
not support error handling (since "then" doesn't accept an errback).  It
unfortunately does support multiple resolution.

This is a modification, allowing for multiple arguments to be passed to the "resolve" method.
