update_firmware support

[seveas]

Apparently there's an UPDATE_FIRMWARE (note: not UPDATE_RIB_FIRMWARE) tag that can be used to update device firmware. If this is non-intrusive, add support for it and somehow update the mirroring scripts/firmware.conf generator to use it.

Hi Seveas,

I just got a chance to try your fix on Python 2.4. Unfortunately, I am now unable to import hpilo:

Python 2.4.3 (#1, Oct 23 2012, 22:02:41)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import hpilo
Traceback (most recent call last):
