Weather refactoring

[fewieden]

• Fixed openweathermap
• Fixed darksky
• Implemented forecast for both
• added indoor values
• documentation
• ...

[fewieden]

Some things are still missing:

• feels like temperature
• openweathermap forecast for newer api keys (grouping 3h forecasts)
• darksky unit handling
• some more config options from the previous modules

But I would categorize those more as improvements.

The build on travis only failed for 50%. Nodejs can't handle class and in the other one the before hooks timed out as seen previously

SUPER AWESOME WORK! 🎉

If we can find a way to make travis happy, I can merge it, and then merge it into develop so we can shift the module as EXPERIMENTAL, which will hopefully increase traction in the development.

I'll be releasing the next MM version January 1st, so lets try to get it included in this version! :)

@MichMich I merged current develop branch (has an updated travis config) into the weather branch. It passed now.
