* [CHD-3464] [Consistency] Fixed a consistency issue where the refresh button on some profiles (e.g. task, worker) said "Reload this ticket" in the tooltip.  This was due to the reuse of text from the translation system.  These tooltips now show 'Refresh'.
* [CHD-3561] [Setup/Mail/Filters] Fixed an issue on the Setup->Mail->Filtering page where 'Create behavior' buttons weren't being displayed for each of the Virtual Attendants listed.
* [CHD-3565] [Virtual Attendants/Comments] The 'New comment on a record' event can now use the comment's parent record or author as 'On:' targets for actions.  These were previously ignored because they are abstract (i.e. they can end up being various record types, and it's not possible for the simulator to know in advance).  The author and parent record of a comment still can't be used in the 'On:' parameter of run behavior, schedule behavior, or unschedule behavior actions; instead, the desired record should be loaded into a private variable of a specific type (using {{comment_record_*}} placeholder fields), and that variable can be used as a target.
* [Comments/Worklists/Choosers] Implemented subtotals, filters, and choosers for comment worklists.
* [Worklists/Export] Fixed errors when exporting virtual fields from a worklist.
* [Virtual Attendants/Comments] When simulating new Virtual Attendant behaviors on the 'New comment on a record' event, a specify comment record can now be targeted for testing.  Previously this wasn't possible due to a lack of comment choosers.
