suggestion: Ctrl-C handler optional in Ice::Application

Hi, Ice::Application is very useful and for this reason there've been a few suggestions before on how to make it more flexible. For example, the callback function interruptCallback() was added in 3.2. Thanks for that, and here's another one :)

Is it possible to make the *installation* of interrupt handler optional? e.g.

Application( bool installCtrlCHandler=true );

Reason: in its current form it's not easy to use it with Qt. We can't block on communicator()->waitForShutdown() in MyApplication::run() because Qt insists on running its event loop in the main thread. So with the Ctrl-C handler installed, one can quit the GUI through the interface but NOT with Ctrl-C inside the terminal -- the expected behavior in Linux.

When buidling a Qt app, one would initialize the modified Ice::Application with a FALSE flag. Hitting Ctrl-C would then kill the GUI, not nicely but, at least, it would work.

We currently fork the standard Ice::Application and do exactly what I described but it's painful to keep this trivial code synched with Ice releases.

Thanks for consideration,
Alex

(By the way, the GUI/Ice example in Connections #12 does not use this class)
