Previous version of a job "Edit Job" on follow page takes you to latest job definition

it's a good question: jobs are mutable, and executions are associated with them. should an execution maintain that association if the job definition changes?

the execution has its own stored details, so viewing an Execution should allow you to re-run using those details. this is what is shown for ad-hoc executions.

I think Job definition and Execution should be more clearly separated. currently the view page for a job execution glosses over the difference by showing the Job header details as if they were directly related to the execution...
