Dev notes

Update emoji class

1. Run $ phing setup update qa and see if you had new emojis (you can also use $ phing emoji:count before and after update)
2. Be aware that emojis can change its name without reason (ex: DIRECT_HIT → BULLSEYE). This forces me to publish a major version 👎.
3. Update Readme: badges, emoji count, ...
4. Update CHANGELOG.md

Cleaning Emoji.php

Emoji.php is generated with descriptive comments for each constant. The comments are striped later to avoid impacting OP_CACHE in production environments.
