Arduino and 1-wire

I have a (simple) working example, that could be added. What is still missing from the library is readout in degrees celsius, I have that too. Also missing is more precise readout. The Application note in which it is explained seems to have disappeared. Except for the keywords.txt I think the library is pretty much done.

It is all jims work, so I guess he will want to pack it up too. Otherwise I will give it a shot. But I need someone to have look at it afterwards.
