/**
* Session Storage and Restoration
*
* Overview
* This service keeps track of a user's session, storing the various bits
* required to return the browser to its current state. The relevant data is
* stored in memory, and is periodically saved to disk in a file in the
* profile directory. The service is started at first window load, in
* delayedStartup, and will restore the session from the data received from
* the nsSessionStartup service.
