    EMailConfigAssistant: Make revising auto-configuration easier.
    
    After providing a name and email address on the Identity page, the user
    clicks Forward and auto-configuration runs.  If successful, it jumps to
    the Account Summary page showing a table of auto-configured settings.
    
    If the user wants to go back and revise auto-configured settings, he
    would click Go Back to return to the Identity Page, then click Forward
    again to go to Receiving Email (since auto-coniguration only runs once).
    
    But this is confusing.  It's not clear that clicking Forward from the
    Identity Page will behave differently after auto-configuration has run.
    Instead, clicking Go Back from the Summary Page after auto-configuration
    should return to the Receiving Email page where IMAP/POP settings can be
    modified.
    
    This behavior combined with the GtkAssistant navigation sidebar should
    hopefully make it less confusing.
