Add named document sets OR add a "reset" button

[jhmann]

As per Christoph's email: please upload named datasets for testing OR please add a reset for testing, so testing changes can be rolled back to the initial uncleaned data set.

I think this is a real (and high) priority, not an enhancement: we need to be able to compare before-and-after states to see if the expected changes in the rule actions are working.

Unless I'm mistaken, a fast fix would be the upload of multiple data sets rather than trying to figure out how a reset button would work. If you name one dataset something like "original-do-not-run-actions", and upload one each for you, Christoph and myself (and any of the others I see on the issue threads?) that we can each run actions on, then we'll each have our own dataset on which to track changes and a common baseline we can compare against.
