Emoji codes support and autocomplete

Odd that we are missing women zombie, its in emoji 5.0, we cover the vast majority of 5.0 :merperson:t5: :elf: etc.

We are tracking it internally now here, it is already assigned: https://meta.discourse.org/t/emoji-5-0-support-is-a-bit-too-patchy-for-woman-version-of-emojis/83534

@Jean-Daniel :woman_zombie: is now in together with the rest of the missing emojis! Thanks for letting us know!
