mod_muc_rtbl: also filter messages This was a bit tricky because we don't want to run the JIDs through SHA256 on each message. Took a while to come up with this simple plan of just caching the SHA256 of the JIDs on the occupants. This will leave some dirt in the occupants after unloading the module, but that should be ok; once they cycle the room, the hashes will be gone. This is direly needed, otherwise, there is a tight race between the moderation activities and the actors joining the room.

summary: |
    Authentication module for 'HA1' hashed credentials in a text file, as
    used by reTurnServer
...

Introduction
============

This module authenticates users against hashed credentials stored in a
plain text file. The format is the same as that used by reTurnServer.

Configuration
=============

  Name              Default    Description
  ----------------- ---------- ---------------------------------
  auth\_ha1\_file   auth.txt   Path to the authentication file

Prosody reads the auth file at startup and on reload (e.g. SIGHUP).

File Format
===========

The file format is text, with one user per line. Each line is broken
into four fields separated by colons (':'):

    username:ha1:host:status

  Field      Description
  ---------- ----------------------------------------------------------------------------------
  username   The user's login name
  ha1        An MD5 hash of "username:host:password"
  host       The XMPP hostname
  status     The status of the account. Prosody expects this to be just the text "authorized"

More info can be found
[here](https://github.com/resiprocate/resiprocate/blob/master/reTurn/users.txt).

Example
-------

    john:2a236a1a68765361c64da3b502d4e71c:example.com:authorized
    mary:4ed7cf9cbe81e02dbfb814de6f84edf1:example.com:authorized
    charlie:83002e42eb4515ec0070489339f2114c:example.org:authorized

Constructing the hashes can be done manually using any MD5 utility, such
as md5sum. For example the user 'john' has the password 'hunter2', and
his hash can be calculated like this:

    echo -n "john:example.com:hunter2" | md5sum -

Compatibility
