/**
* nsIObserver topics for profile changing. Profile changing happens in phases
* in the order given below. An observer may register separately for each phase
* of the process depending on its needs. The subject passed to the observer's
* Observe() method can be QI'd to an nsIProfileChangeStatus.
*
* "profile-approve-change"
* Called before a profile change is attempted. Typically,
* the application level observer will ask the user if
* he/she wants to stop all network activity, close all open
* windows, etc. If the user says NO, the observer should
* call the subject's vetoChange(). If any observer does
* this, the profile will not be changed.
*
* "profile-change-teardown"
* All async activity must be stopped in this phase. Typically,
* the application level observer will close all open windows.
* This is the last phase in which the subject's vetoChange()
* method may still be called.
* The next notification will be either
* profile-change-teardown-veto or profile-before-change.
*
* "profile-change-teardown-veto"
* This notification will only be sent, if the profile change
* was vetoed during the profile-change-teardown phase.
* This allows components to bring back required resources,
* that were tore down on profile-change-teardown.
*
* "profile-before-change"
* Called before the profile has changed. Use this notification
* to prepare for the profile going away. If a component is
* holding any state which needs to be flushed to a profile-relative
* location, it should be done here.
*
* "profile-do-change"
* Called after the profile has changed. Do the work to
* respond to having a new profile. Any change which
* affects others must be done in this phase.
*
* "profile-after-change"
* Called after the profile has changed. Use this notification
* to make changes that are dependent on what some other listener
* did during its profile-do-change. For example, to respond to
* new preferences.
*
* "profile-initial-state"
* Called after all phases of a change have completed. Typically
* in this phase, an application level observer will open a new window.
*
* Contexts for profile changes. These are passed as the someData param to the
* observer's Observe() method.
* "startup"
* Going from no profile to a profile.
*
* The following topics happen in this context:
* profile-do-change
* profile-after-change
*
* "shutdown-persist"
* The user is logging out and whatever data the observer stores
* for the current profile should be released from memory and
* saved to disk.
*
* "shutdown-cleanse"
* The user is logging out and whatever data the observer stores
* for the current profile should be released from memory and
* deleted from disk.
*
* The following topics happen in both shutdown contexts:
* profile-approve-change
* profile-change-teardown
* profile-before-change
*
* "switch"
* Going from one profile to another.
*
* All of the above topics happen in a profile switch.
