mod_invites_page: Remove preauth URI button This button is incompatible with the majority of XMPP clients around, yet based on feedback from users, many are drawn to click it when they have any XMPP client installed already. In the case where the user already has software installed, we would prefer them to select it from the software list so they can follow the setup process suited to their specific client (we already track which software supports preauth URIs). If their client is not listed, they can still use the manual registration link instead.

# Introduction

This module prevents unaffiliated users from sending private messages in
chat rooms, unless someone with an affiliation (member, admin etc)
messages them first.

# Configuration

The module doesn't have any options, just load it onto a MUC component.

``` lua
Component "muc"
modules_enabled = {
    "muc_block_pm";
}
```
