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.

Also add a model for registering an alias for an affiliation so that
we can group affiliations that are considered the same for statistical
purposes, and a model for registering unimportant endings like Inc.
and GmbH.
Affiliation grouping is done through three means: stripping
uninteresting endings, merging entries that only differ in case and
aliases that map from case-insensitive alias to name.
Stripping endings and merging based on case seem to reduce the number
of needed manually maintained aliases greatly.
