case we can't parse it and it's not empty, add page with list of
countries (to be able to refer people to it), add ISO codes as country
aliases - the country alias code is now more intelligent with respect
to case so it's easier to keep these aliases explicitly

to the draft parser (incorporating patch from trunk), store the
extracted country instead of trying to turn it into an ISO country
code, add country and continent name models and add initial data for
those, add helper function for cleaning the countries, add author
country and continent charts, move the affiliation models to
stats/models.py, fix a bunch of bugs.
