mod_http_oauth2: Implement refresh token rotation Makes refresh tokens one-time-use, handing out a new refresh token with each access token. Thus if a refresh token is stolen and used by an attacker, the next time the legitimate client tries to use the previous refresh token, it will not work and the attack will be noticed. If the attacker does not use the refresh token, it becomes invalid after the legitimate client uses it. This behavior is recommended by draft-ietf-oauth-security-topics

# mod_tweet_data

This module adds [Open Graph Protocol](https://ogp.me) metadata to Twitter.com tweet URLs sent inside a MUC.

It's similar to [mod_ogp](https://modules.prosody.im/mod_ogp.html) but is adapted specifically to Twitter.com, which doesn't support the [Open Graph Protocol](https://ogp.me).

When a user sends a tweet URL in a MUC (where the message has its `id` equal to its `origin-id`), this module calls that URL to get the tweet data.
If it finds any, it sends a [XEP-0422 fastening](https://xmpp.org/extensions/xep-0422.html) applied to the original message that looks as follows (note, I haven't used real data here):

```xml
    <message xmlns="jabber:client" to="user@chat.example.org/resource" from="chatroom@muc.example.org" type="groupchat">
        <apply-to xmlns="urn:xmpp:fasten:0" id="82dbc94c-c18a-4e51-a0d5-9fd3a7bfd267">

Configuration
-------------

You'll need to provide a Twitter APIv2 bearer token.

```lua
Component "muc.example.org" "muc"
  modules_enabled = { "tweet_data" }
  twitter_apiv2_bearer_token  = { "some-very-long-string" }
```
