Update system monitor.

Overall cleanup, and modificaton to the disk chart.  System tracks Byte,
KiB and MiB transfer rates.  Can't realld support GiB because I'm no
sure the PCIe bus can handle that.

Modifed the Y-Axis for disks so it displays the data on the closest
power of 2 scale. Seems to be a reasonable way to modify the scale so we
can actually see some of the smaller writes.
