Use Ipsilon specific PAM service file
    
    Ipsilon was using the 'remote' PAM service file but that was causing
    conflicts so instead instead install a 'ipsilon' PAM service file
    whose initial contents exactly matches the contents of the 'remote'
    service file. All references to the 'remote' service file were
    replaced with 'ipsilon'.
    
    Because the pam service file is shared between both the form and pam
    login managers it's not possible to have just one of the login
    managers install the pam service file. The co-dependance problem is
    solved by always installing the pam service file irrespecitve of
    whether the form or pam login managers are used. The presence of an
    unreferenced pam service file is considered begin.
    
    The ipsilon pam service file is located in the source disttribution as
    a template file, templates/install/pam/ipsilon.pamd. All files under
    templates/install are installed under /usr/share/ipsilon. The RPM will
    copies templates/install/pam/ipsilon.pamd into /etc/pam.d/ipsilon when
    the base package is installed.
