Title: Change example to not include legit-random-looking cookie secrets

Not that it's happened to anyone we know, or anything like that, *cough* — but if one were to copy-paste some example code and build a project out of it, you really wouldn't want to accidentally launch a thing using an insecure/publicly posted cookie secret that anyone could find in the examples.

This makes it blatantly obvious to anyone reading the code that the cookie secret is insecure and should be changed. (I think the most important place is the overview page, but I also changed the examples.)
