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 support for advertising the language used in a room.
# Configuring
``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
"muc_lang";
}
```
The room language is specified in a new field in the room configuration
dialog, accessible through compatible clients.
Use [language codes](https://en.wikipedia.org/wiki/ISO_639) like `en`,
`fr`, `de` etc.
# Compatibility
Meant for use with Prosody 0.10.x
Native support was [added in Prosody
trunk/0.11](https://hg.prosody.im/trunk/rev/9c90cd2fc4c3), so there is
no need for this module.
