Subject: [PATCH] Vape mode: Changes to behaviour

- Only tunes that sync with the level will change in speed. This means it will not apply to jingles or Stereo Mode.
- In Versus mode contexts, Vape Mode makes way for nightcore.
    - This is a roughly 15% increase, the inverse of the standard encore multiplication.
