Made AskFile* dialogs movable-modal by default, by providing a dummy

eventProc (which simply drops all events on the floor). Also added a
method SetDefaultEventProc through which frameworks can set a global
event handler (which can still be overridden on a per-call basis
with the eventProc argument).
