mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.

summary: Drop chat states from messages to inactive sessions
...
Introduction
============
Some mobile XMPP client developers consider [Chat State
Notifications](http://xmpp.org/extensions/xep-0085.html) to be a waste
of power and bandwidth, especially when the user is not actively looking
at their device. This module will filter them out while the session is
considered inactive. It depends on [mod\_csi](/mod_csi.html) for
deciding when to begin and end filtering.
Configuration
=============
There is no configuration for this module, just add it to
modules\_enabled as normal.
Compatibility
=============
