mod_pubsub_mqtt: Switch to MQTT 3.1.1 Well that was easy.

mod_pubsub_mqtt: Support atom_title payload type This commit adds the ability to publish and subscribe with arbitrary payload types. It has a breaking change, which is that topics are now of the form: HOST/TYPE/NODE Currently supported types are utf8_data, json and atom_title.

mod_pubsub_mqtt: Fix some inappropriate log levels

mod_pubsub_mqtt: Add XEP-0060 <item> wrapper to payloads

mod_pubsub_feeds: Include feeds library in plugin package Thanks drsnuggles

mod_http_muc_log: Fix syntax error in timestamp adjusting script Put the } on the wrong line. Praise the Lua `end` !

mod_http_muc_log: Move language attribute onto body itself One could argue that it's mostly the message that is in a particular language, while the timestamp is less so. What language a particular nickname is, and its relation to the language in the text, that is an unresolved question.

mod_http_muc_log: Tweak style towards the "modern" Also accidentally converted the hand-minified CSS to SCSS for easier editing. This gets rid of the <q> element because it makes browsers (at least Firefox) add annoying quotes to any text copied out of them, interfering with opening non-linkified URLs. That could have been considered a sort of security mechanism, but convenience trumps security!

mod_http_muc_log: Fix error in js when displaying presence is disabled When the form is hidden, attempting to index forms[0] throws an error, however this is harmless since the script is finished by that point.

mod_http_muc_log: Include static resources (css & js) in plugin package Forgot to include this in the previous commit somehow.
