[Xastir] Xastir + One Wire Weather (OWW)

[Phil - w2lie]

Dana,
Thanks, I've already applied that hack, but it isn't sending out my 
Humidity readings at all.   The Gusts and total rain values are also not 
working properly.

Any clues on how to patch OWW to make it work?  I sent a QST out on the 
1-wire weather group, but I got nothing over there but crickets.
