Trello integration.
You'll need a Trello API key. You can get it `here
<https://trello.com/app-key>`_.
You'll also need an auth token if you want to view/change private
resources. You can generate a permanent token linked to your account on
``https://trello.com/1/connect?key=<KEY>&name=platypush&response_type=token&expiration=never&scope=read,write``.
Also, polling of events requires you to follow a separate procedure to
retrieve the Websocket tokens, since Trello uses a different (and
undocumented) authorization mechanism:
1. Open https://trello.com in your browser.
2. Open the developer tools (F12).
3. Go to the Cookies tab.
4. Copy the value of the ``cloud.session.token`` cookie.
