*  DESCRIPTION:  Dialog for configuring UPS service behavior:
*                                       - display popup messages on power failure
*                                       - wait X seconds before displaying warnings
*                                       - repeat warning messages every  X  seconds
*                                       - shutdown X minutes after power fails
*                                       - ALWAYS shutdown when low battery
*                                       - execute a task before shutdown
*                                       - turn off the UPS after shutdown
