Updates to merge in latest nalanda-rct3 to central.

@dylanjbarth, let's chat about this tomorrow. I don't think I've found the latest code of yours, or I've missed something in how to make it work. See the screenshot below (don't see a way to export anything other than tests). Also, the " Export data" button on a Facility management page seems to still do the old behavior (slides out with a date range request form).
