    user-accounts: add "Other Passwords" button
    
    Since the user can change the login password from
    the user panel, it stands to reason the user may want
    to be able to adjust other passwords from there as well.
    
    This commit adds an "Other Passwords" button which runs
    seahorse when clicked.
