* [Virtual Attendants/Workers] The 'Set (variable) worker' action of Virtual Attendants is now capable of including additional lists of workers using behavior variables.  This is useful when workers are being included from an external source like the ShiftPlanning plugin, and the 'set worker' action is picking one of them with a load balance, random, or round robin strategy.  This also provides a cleaner way to select a worker from a subset based on any criteria that isn't handled by the action now: skills, location, language, etc.
* [Virtual Attendants/Simulator/Workers] The simulator for the 'set (variable) worker' action will now show worker names instead of IDs.
