> PIVOT-916 regularized the handling of uncaught exceptions in most places in the GUI thread
and during startup.  But background threads can still basically ignore uncaught exceptions.
 But using the Thread.setDefaultUncaughtExceptionHandler and changing some of our interfaces
(namely Application.UncaughtExceptionHandler) we could use the ApplicationContext.handleUncaughtException
as the default exception handler (which delegates to an application's override method).
> This would involve changing the signature (or adding an override method) that accepts
(Thread, Throwable) in both ApplicationContext and Application.UncaughtExceptionHandler interface.
