Redesigning UI, moving code to final server environments

There's a lot of changes in here - the two big ones are moving the application to its final home (at the root of oastats*.mit.edu, rather than in a directory on libraries*.mit.edu). The second is a wide-ranging list of UI changes after consultation with Sean and Sands - the ListBuilder plugin is gone, and there's a great deal of other stylistic changes.

Other changes include adding the countries.json file from mledoze for better map performance, and making the author view more relevant.
