* [Activity Log/Code Cleanup] Fixed the default labels for Activity Log entries when used in Virtual Attendant behavior.
[Code Cleanup/KB] Tweaked the KB's workspace tab to 'Knowledgebase Browser' from 'Browse KB' so that its alphabetical order in the tab-type list was more appropriate.
* [Translations/Localization] Updated the Portuguese translation (Thanks to Weblevel.pt!)
* [Virtual Attendants/Code Cleanup] Fixed a bug in the 'abstract list' condition in Virtual Attendant behaviors.  It's unlikely that this affected anything in production, but new functionality uses this template to present arbitrary lists to the user for making multiple selections in VA outcomes.
* [Virtual Attendants/Code Cleanup] Fixed a bug in the 'Send Mail' action of Virtual Attendant behaviors that prevented the 'From:' address from being set properly in some cases.
* [CHD-3277] [Dashboards/Worklists] The placeholder for 'Current Worker' may now be used when filtering dashboard widgets; including worklists, gauges, charts, and counters.
