Allow binding to a channel whose type is a supertype of the source.

[GoogleCodeExporter]

 If I have a FieldModel<U> f and a Channel<Object> c, I'd like to be able to do :

binder.bind(f).to(c.asDestination());

I join a patch that changes de signature of asDestination to:

<U extends T> Destination<U> asDestination();

 Another solution (as Andrew suggested), is to change the signature of 'to' to be:

public void to(final Destination<? super T> destination)

I've added <? super T> to the various bindings (Channel builders and 
ValueBindingBuilder).  This is in svn and the current 0.8 snapshot.
