remove emoticons option

- Nowadays, messages can contain both unicode emoji and text smileys.
- This extension/options doesn't bring a real added value IMO. Moreover it had
  to be enabled by the user to be effectiv to be effective
- the emoticons js scripts contained pictures licensed under CC-BY-SA-2.5 which
  is not DFSG compatible. See:
