Add emojis of Unicode 7, 8, 9 and 10 to en-US autocorrection

also fixing some old shortcodes.

Testing the new emojis in an en-US document:

🕊 → 🕊

🍿 → 🍿

:spock: → 🖖

🦄 → 🦄

Note: only translations are added to the autocorrection,
so there won't be untranslated strings in a non-en-US
autocorrection table.
