Re-enable mass download from search results list?

I .seem to remember it was disabled due to being terribly slow...and then never improved...

Building an archive was taking forever. We need to fix this. I'll think about the problem and will propose a solution.

Note from Bob:
Suppose I did a search as below and have found some data records. How do I download all the amc or dif or cifs, etc from this search? We were able to do this in the old database, but I do not see how to do it now.
