Title: Feature/view logging

Implements basic logging of downloads and views. All impressions are 'unique' w/r/t session id.

Views are logged on pulling up the show page for a NuCoreFile.

Downloads are logged on downloading an item either through the shopping cart or directly from the shop page, and are tracked on individual records.
