Fetch the firmware update and extract the needed audios.bin firmware.
Fetch the firmware update and extract the needed audios.bin firmware.

Basic idea:

1) Fetch the latest SystemUpdate.zip from Microsofts update servers
2) Unzip the update package
3) Download Rene Ladan's extract360.py script (which, for the record, is licensed under the BSD 2-clause license)
4) Use extract360.py to extract audios.bin from the containing file from the update package
5) Clean up everything

I may reimplement this all in Python later, since we depend on Python for
the extraction anyway, so as to eliminate the wget and unzip dependencies.
