#167 Dummy view for importing committees and countries via admin panel.

Adjusted the admin view to load csv files. Things still to do: write a unit test, and make it functional (it currently returns an index error because the csv reader returns an empty list).
I don't actually know what format the CSV file will be in when you receive it from the request (I'm guessing it's a string?). But you should make sure. It will determine how to use `csv.reader`, since I believe it's conventionally supposed to take a file.
