weather: forecast up to 10 days

This service needs api key. For now I put it straightly into the url
It will need to be replaced, like in perl with {{ENV_APIKEY}} , but not sure if python supports this. Gonna look at it deeply.

Any particular reason for this? Per [requests homepage](http://docs.python-requests.org/en/latest/) there should be a thing `r.json()`. That way you do not really need to import `json` and the whole point of this function is doing that timeout thingy.
