Title: Preferences.voice sustain

I allowed a user to determine whether voices were sustained through the current interaction.

I added three actions.
* Preference("voice sustain", "enable") - Sustain voice through the current interaction.
* Preference("voice sustain", "disable") - Don't sustain voice through the current interaction.
* Preference("voice sustain", "toggle") - Toggle sustain voice.
And I used all_character_callbacks to implement this future.
Default to False
