Facebook - Set everything to "Only me" (private)

facebook-private-everything.js

/*
This script sets every post on your Facebook profile to "Only me".
It's very hastily thrown together and will most certainly break in the future, but it should at least provide a starting point for anyone else who wants to do this.
Make sure to change your name below before running.
Run by just pasting into the JS console.
