database (iddata_clean), and a script to generate fake idle entries for
testing scripts on the minibed (idloadup.pl).

iddata_clean, by default, removes all idle entries older than 36 hours.
This can be changed by providing -m <maxage> (in seconds) to it.

idloadup.pl adds random idle data at time offsets from now, to 5 days
prior (1 sec granularity).  It adds anywhere from 1 to 10 entries per
PC to the node_idlestats page, and from 1 - 10 x # interfaces to
the iface_counters table.
