Adding detail regarding which galley was viewed, downloaded

[hlflanagan]

We'd like more detail regarding which galley was viewed and/or downloaded for each article. We are about to kick off a project to translate all the articles in our backlog, and it would be great if we could tell whether or not the translations are being used.

I can imagine this as detail in the downloaded .csv file, with the web page display having only the aggregated numbers like it does now, or updating both to include the following columns:

Title	Section	Date Submitted	Date Accepted	Date Published	Days to Publication	Views (Display Galley)	Views ($language_tag)	Downloads (Display Galley)	Downloads ($language_tag)
