added ability to download full audios from tiktok (3.3.5)

- it's now possible to download full audios from tiktok videos, you just have to turn that on in settings.
- tiktok audios are better in quality when it's possible to get exact audio used in video and not the full version of it.
- cleaned up the way user preference stuff is passed over between modules, should be way more flexible now.
- added audio ignore list to services config json instead of hardcoding it.
