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 allows you to make one or more MUCs as accessible to local users only.

# Details

Local users (anyone on the same server as the MUC) are granted automatic
membership when they first join the room. Users from other servers are
denied access (even if the room is otherwise configured to be open).

# Configuring

## Enabling

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

## Settings

Specify a list of MUCs in your config like so:

```
muc_local_only = { "my-local-chat@conference.example.com" }
```

# Compatibility

Requires Prosody 0.11.0 or later.

# Future

It would be good to add a room configuration option.
