Add per-run comparisons

Not sure if this is already supported:

The "test history" view has a row per job, and allows comparisons between jobs. 
 Is there an option to show a row per run, so I can easily compare runs between 
jobs?  E.g. job A's run 3 v.s. job B's run 2, etc.

Similarly, the "test results" page could have a checkbox next to each run (e.g. 
just right of the "Run N:"), so users can easily compare runs within the same 
job, perhaps pre-checked so (by default) "Compare" will compare all runs for 
that job.
