Feature: emoji editor (#2411)

Browse Source 
* Custom emoji editor: implement backend

This reuses the logo upload code

* Implement emoji edit admin interface

Again reuse base64 logic from the logo upload

* Allow toggling between uploaded and default emojis

* Add route that always serves uploaded emojis

This is needed for the admin emoji interface,
as otherwise the emojis will 404 if custom emojis are disabled

* Fix linter warnings

* Remove custom/uploaded emoji logic

* Reset timer after emoji deletion

* Setup: copy built-in emojis to emoji directory
