First release

This release works for ps/2 keyboards and mice, and serial mice. When these device are inactive (they do not generate interrupts as detected in /proc/interrupts), rtcidle calculates the wakeup time as two minutes before the next job in the at or cron queue, sets the rtc alarm at two minutes before this job, and enters the suspend state using either apm or acpi (whichever is available). Suspension is not done if any of a number of programs are running; these programs can be specified in a configuration file; this allows for example to avoid suspension when 'cdrecord' is active, even if the user is not (this would cause wasted media); this also allow the cron or at jobs not to be interrupted by suspension one they are started.
