Configuration of the 1-wire drivers won't be needed

[starksm64]

The raspbian image I will burn onto the sdhc card we give out will already have the 1-wire overlay and drivers enabled, so the user will not have to actually make that change and reboot their device to get going. We can mention such a change is necessary over the default raspbian distribution, but they won't have to do it.

Change is in pull request #3.

Makes sense to me - I was mostly just taking notes so I could remember what I had done :-)
