Title: Add import to jsonify example

I am new to flask and it took me half an hour to figure out why jsonify doesn't work for me. So answer has pointed out solution for me: http://stackoverflow.com/questions/10727366/jsonify-is-not-defined-internal-server-error . I thought that this import line in example can help out newcomers, like me, in a future.
