Revised version of Remastering HowTo

[utu]

First of all you have to copy the new ISO to the directory of isoimages from VirtualBox.

You will be amused to know that I just used my LiveCD, not an iso,
and told VirtualBox where my guest OS source was to be found.
A few snapshots later I had something like my LiveUSB up and
running, albeit with a few hardware emulation errors.
I didn't know that was the wrong way to go about things.

I'll stop troubling you with all my growing pains.
Thanks for getting me going on both VirtualBox & re-mastering.
