power.d script for autosuspending USB bluetooth devices

From https://launchpad.net/bugs/911325:

Colin King spent some days doing extensive and accurate power benchmarking [1],
amongst others the effect of the low-power modes of various hardware.

Here are two scripts which handle USB bluetooth adapters and a subset of PCI devices which are safe to turn into low-power mode.

Typical savings: 0.38 W per machine with some machines seeing > 1-2W savings.
