Fix some bugs in double playback speed.

- Apply double speed for all voice tracks, not only for the current.
- Use dedicated atomic in Mixer for the voice speed (fix race).
- Store the playback speed in user settings, not in global settings.
- Use float64 for setting (just consistency, no float-s right now).
