deferReadiness() to load current user

ember_initializer

/* 
 * This was the quickest way I could figure out how to load
 * the authenticated user into the app. It would make more sense
 * if I only made one query to the server for the authenticated user
 * (I could put the user id into a hidden input and load it from there)
