Add support for Wemo Humidifier

[Adam Belebczuk]

Hi all, would it be possible to add support for the Wemo Humidifier?

Product Page:

Another project trying to implement local control of the humidifier:

As long as the same protocols are involved, it should be reasonably straightforward. Adding new types is pretty easy, although the API and CLI get a little messy. I'd love to refactor it all, but there's just no time.

Anyway, it is certainly possible, and I would happily assist anybody who wanted to do so.

I've created a pull request to add this to pywemo: pywemo/pywemo#87. Feel free to roll the changes into ouimeaux as well.
