Title: Download zip (rebased onto develop)

This is the same as gh-1574 but rebased onto develop.

----

Fix the remaining problem when downloading the zip directly from the activity window. (see https://trac.openmicroscopy.org.uk/ome/ticket/9961)

To test:
* Create a zip using the ```Batch Export``` script (select one image).
* Download the result from the activity window.
* Create a zip using the ```Batch Export``` script (select 2 images).
* Download the result from the activity window. A dialog should pop up to indicate that a file with the same name already exists.
