* speechDictHandler.reflectVoiceChange now can accept None as synth parameter, in this case it will use synthDriverHandler.getSynth() to receive current synth
* SmartDictionaryManagerDialog.onClose now calls speechDictHandler.reflectVoiceChange() to update list of smart dictionaries are currently processing. This fixes an issue creating new or deleting an existing dictionary causes no effect before changing current voice or synthesizer
