Also: All script tasks should raise WorkflowTaskExecExceptions - NOT APIExceptions - this is because our scripts are executed by Spiff (not the other way around) so the errors need to pass fluidly through spiff, and come back to use THEN we can convert them to APIErrors. Otherwise we lose all kinds of good information about the error.
Modifed the request_approval to take a list of arguments, which works better for us... today.
UpdateStudy correctly handles validation.
WorkflowService correctly populates random values from lookup tables.
And several fixes down in Spiffworkflow, including a big bug where only the last item in a decision table made it through.
Fixing a bug where the validation of forms did not correctly process auto-complete fields.
Fixing a bug where the approvals script and the update study script could not process dot notation correctly.
Moved populate_random_data into the WorkflowService where it makes more sense.
