This backend will listen for events on a Pushbullet (https://pushbullet.com)
channel and propagate them to the bus. This backend is quite useful if you
want to synchronize events and actions with your mobile phone (through the
Pushbullet app and/or through Tasker), synchronize clipboards, send pictures
and files to other devices etc. You can also wrap Platypush messages as JSON
into a push body to execute them.
Triggers:
* :class:`platypush.message.event.pushbullet.PushbulletEvent` if a new push is received
Requires:
* **requests** (``pip install requests``)
* **pushbullet.py** (``pip install git+https://github.com/rbrcsk/pushbullet.py``)
