Export of import logs don't match any URL string, possibly since they were put into date folders in commit d5dde08 in July 2014, which seems a bit weird...
Refs #344 by referring to task_id for log in link rather than the filename, and creating a new view to process the download based on the export download view. Needs testing.

Changed link URL and fixed error in view, now works, fixes #344
