Easy access to providers for a Set multibinding

_From [chrisn@google.com](https://code.google.com/u/110897298328163008227/) on May 04, 2011 13:10:43_

MapBinder provides a Map<K, Provider<V>> in addition to Map<K, V>. It would be nice if Multibinder provided a Collection<Provider<V>> (or List) in addition to Set<V>.

I've attached a proof of concept module that implements this using the SPI.
