mod_http_oauth2: Add role selector to consent page List includes all roles available to the user, if more than one. Defaults to either the first role in the scope string or the users primary role. Earlier draft listed all roles, but having options that can't be selected is bad UX and the entire list of all roles on the server could be long, and perhaps even sensitive. Allows e.g. picking a role with fewer permissions than what might otherwise have been selected. UX wise, doing this with more checkboxes or possibly radio buttons would have been confusion and/or looked messier. Fixes the previous situation where unselecting a role would default to the primary role, which could be more permissions than requested.

# Introduction

This module adds a room configuration option to hide inline media from MUCs and
display them as links instead.

This can be useful in public channels where content posted by users should not
be shown by default.

**Note:** You could consider the more useful [mod_muc_restrict_media] instead,
which allows affiliated users (e.g. members, admins, owners) to still send
inline media.

# Configuring

## Enabling

``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
    "muc_hide_media";
}
```

## Settings

A default setting can be provided in the config file:

``` {.lua}
muc_room_default_hide_media = true
```
