qt: clean up initialize/shutdown signals

Browse source 
- Change initializeResult(int) to initializeResult(bool) to avoid
   implicit type conversion.
 - Use EXIT_FAILURE and EXIT_SUCCESS instead of magic numbers.
 - Remove the argument from shutdownResult(int); it was called with a
   constant argument.
