Smelty on the Belty returns

- Encased fans now work on the "fake items" moving on the belt
- Chunk no longer redraws when TEs send data. (May break stuff)
- Regular fan particles are less noisy
- Items no longer spazz out when the belt is stopped
- Fixed extractors waiting indefinitely if belt is occupied
