Harshit Bansal 7950f82f27 realm_emoji: Make sure that a deactivated realm emoji can't be used. 
A deactivated realm emoji should neither be accepted further as a
reaction nor its further occurences in a message be rendered as an
emoji. However, all the old occurences should continue to render
normally.

then, an emoji author must be allowed to delete an emoji uploaded
by them.

Harshit Bansal 40d137d621 bugdown: Change rendered emoji image to `unicode/<codepoint>.png.` 
Use `name_to_codepoint.json` file (and the similar structure in
emoji_codes.js) to map emoji names directly to codepoints and change
the rendered emoji image to `unicode/<codepoint.png>` rather than
`<emoji_name>.png`.

Fixes: #3539.
