[Fix] for Events-3.2 and Zurgle

I've been running with Zurgle, and then filed in Events-3.2.cs from
Ned Konz to switch to the newer event model, and I couldn't pop up the
Zurgle preferences.  As far as I can tell, Morph>>updateableActionMap was
not returning the new ActionMap.  It seems that setProperty should return
the property value, but I couldn't figure out why it wasn't.

The fix just assigns to ActionMap to a temp variable, then returns it.
There may be a better way, but this gets me my preference dialog back.
