Diagnostics for Expression Slot evaluation were added. The following categories were added to the Simulation, Rulebased Simulation and Workspace diagnostics settings dialog.

The Simulation and Rulebased Simulation setting control diagnostics issued during a run of the appropriate expression slot evaluation times (i.e. before or after timestep, before or after run). The Workspace categories apply to expression slots evaluated outside of a run, that is, when you evaluate a slot expression manually via the open slot dialog or from the workspace.
