commit 572844ab2157f1837f5ca53a77234f13f54e27c4

    Prefer Yahoo! Weather over Yr.no if available and enabled.
    
    Yahoo! Weather has better data (it provides minimum and maximum temperature,
    for one), and we can know for sure if it's going to work or not, so we can
    easily fallback on yr.no
