Yahoo weather update

We just released a new version of the Yahoo weather service.

– If yahoo is down or doesn’t respond to the weather update request, we ignore the update until the connection succeeds again.
– The status updates are now written to the logs, so you can see when it failed
– We’ve written a manual inside the Yahoo Weather service, use the small bleu information button for instructions on how to use.

We intend to document all services much better from now on.
