Support fedibird emoji reaction

[shuuji3]

Some Mastodon-fork or other Fediverse servers support Emoji reactions but Elk cannot show any of them now.

Although the full support for non-Mastodon feature from Masto.js is still under discussion (neet/masto.js#939), Phanpy already partially supports it (read-only for now). And the required data is already in the API response. The following example is the response used in Elk from Mastodon-fork server (fedibird.com):

{
    ...
    "url": "https://fedibird.com/@shuuji3/113389571124564820",
    ...
    "emojis": [
        {
            "shortcode": "fedibird_role_01",
            "url": "https://files.mastodon.social/cache/custom_emojis/images/000/742/119/original/2fa7c5a158722c9d.png",
            "static_url": "https://files.mastodon.social/cache/custom_emojis/images/000/742/119/static/2fa7c5a158722c9d.png",
            "visible_in_picker": true
        }
    ],
    ...
}

I think this feature has been there for a long time and is enough stable, so Elk also can support some of them at least as a read-only feature like Phanpy. This will reduce the hurdle of using Elk for users in such servers.

There was a misunderstanding. The above emojis fields only include the emoji information used within the body text, not emoji reactions. So additional data needs to be fetched from another place.

The remoji_reactions property can be by fetching the status from the original fedibird server. In this case, it's https://fedibird.com/api/v1/statuses/113389571124564820
