Emoji in the Codex!

Currently the new emoji in WordPress 4.2 aren’t documented anywhere. I found this very confusing when trying to figure out how to use them. This is a great time to get rid of the old Using Smilies page and have a new user-facing emoji page.

This needs to be done asap so we can include a link to it in the new release.

The page should contain the following:

1. Short intro to emoji
2. Short section on emoji on mobile
3. Short section on emoji on desktop (including the shortcuts on each platform to bring up the emoji popup)
4. List of common emoji/smilies

Anyone interested in volunteering? We need it pretty quickly so we can add a link to it in 4.2.
