Dashboard audit logs and workflow integration

New audit log emitted for dashboard downloads: Downloading dashboards as PDF now triggers the audit log event triggerDashboardSnapshot. Dashboards are supported as a task type in workflows: Create a job task with the Dashboard task type to refresh dashboard results and optionally send subscription emails. Calculated measures from dashboards better supported: Genie Spaces created from dashboards are now better able to use any calculated measures defined on the dashboard.
