query logger should be registered directly on dispatcher

We were accidentally registering the listener on the shared dispatcher
multiple times - once for each connection.  This caused duplicate query

 - Overhauled ufAlerts, improving efficiency, reliability, and fixed a discovered edge case that caused `render` to never complete. (part of #646)
 - ufAlerts will only auto-scroll when outside the viewport (even if only partially). Can be overriden with `scrollWhenVisible: true`. (#714)
 - Rebased ufCollection, and ufForm with new jQuery plugin template. (part of #646)
+- Fix issue with duplicate query logs when using multiple databases
 
 ## v4.0.20-Alpha
 - Remove pivot columns from pagination subquery in BelongsToManyThrough, to deal with MySQL's `only_full_group_by` warning
