[epiphany] Add a 'crashed' option to the session restore policy

    Add a 'crashed' option to the session restore policy
    
    With this policy the session will only be restored if the application
    has exited unexpectedly, but not if the user manually closes it.
    
    There are no code changes needed for this to work, having a (valid)
    different value than always/never in the setting makes things just
    work.
