mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel) Otherwise the global event handlers accumulate, one added each time logging is reoladed, and each invocation of the signal or event triggers one dump of each created ringbuffer.

# Introduction

This module adds an internal Prosody API to retrieve the last displayed message by MUC occupants.

## Requirements

The clients must support XEP-0333, and the users to be tracked must be affiliated with the room.

Currently due to lack of clarity about which id to use in acknowledgements in XEP-0333, this module
rewrites the id attribute of stanzas to match the stanza (archive) id assigned by the MUC server.

Oh yeah, and mod_muc_mam is required (or another module that adds a stanza-id), otherwise this module
won't do anything.
