lkk Reimplement to fix app shutdown problems
This is called:
1) when a usecase is at EOF
AND there are no more usecases
2) when a recorder is active
etc. (I don't really understand the complex state when this is called.)
Also, the generic code in guishared is gtk specific and doesn't remove the replayer idleHandler,
only sets the local self.idleHandler = None (and the idleHandler stops later when it gets
the return value of False.)
For our purpose, insure the replayer idleHandler is stopped and don't start the describeHandle
if the app is trying to quit.
'''
"""
The problem with app shutdown was fixed by adding app.quit() to SUT.
The problem was that automatic shutdown on last window closed did not shutdown app.
Possibly because still timers in the event loop?
Anyway, the solution of calling app.quit on main window close in the SUT
allows the default implementation of tryAddDescribeHandler to work.
We don't need what follows, which was an attempt to make sure there are no timers left in the event loop.
I leave this cruft here because I still don't understand why the describeHandler is reinstalled
and if it is preventing automatic app shutdown on last window close.

Boolean result of replayIdleHandler.
For GTK:
- True causes the handler to continue, i.e. get called again next iteration of event loop.
- False is the opposite, i.e. stops the idle handler.
For Qt this is moot (but function must be implemented, its pure virtual in the base class?)
However, see elsewhere for how Qt handlers are stopped.
