There is already a ResultAdapter in util/ that adapts an
invocation service ResultListener into a com.samskivert.util.ResultListener.
Flash can't cope with two classes of the same name in the same library
module, so I named my adapter *Wrapper. For consistency it would be nice
if these were the same in ActionScript and Java, so maybe we'll end up
just renaming the one in util/.
