Links for generated files aren't working

Steps to reproduce the problem:

• Use the CSV importer to import the Belize sample file into Iris, and wait for the background jobs to run. gford-20140000-010015_belvegr.zip
• In the Aster UI, view the page for the Belize record.
• When I click the 'Download Shapefile' drop-down, and select 'Download Shapefile' from the 'Original' section, I can successfully download the zip file.
• When I click the 'Download Shapefile' drop-down, and select 'Download Shapefile' from the 'Generated' section, I just get a spinner that never resolves, and I'm unable to download the file.
• I see the same problem if I try to download the generated KMZ or GeoJSON files.

Ok, the problem is that this directory doesn't exist, and geoblacklight and/or aster don't create the directory for you. Once you create the directory, then the generated files downloads works.

[Rails root]/tmp/cache/downloads or whatever is set for DOWNLOAD_PATH in aster's config/settings.yml

Here's what we need to fix the problem in our sandbox and demo environments:

• Update the aster provisioning scripts to mkdir the downloads directory
