An handler get added each time a topic is loaded to the window object
jQuery resize api only pass data to the handler when triggered.
```.resize( [eventData ], handler ) ```
The unbind followed in willDestroyElement had no affect.
.on(...) or bind(..) support the event.namespace
fix was not tested.
- unread was not incrementing when you read last post on topic
- new notifications were being inserted even if they existed in list
- terminology was all mixed up "1 new posts", split to 3 messages
- latest behaves as expected, updating count of new and updated topics
