Subject: [PATCH] Initialize pointers to null on creation

Fixes access violation in hello_world.ppu.elf on window close.
As I understood the reason - when dtor of XAudioThread is called it
checks:
if (m_source_voice) Quit();
But m_source_voice isn't initialized to 0 by default so when in Quit()
in tries to call some funcs from unitialized ptrs and access violation
happens.
