Feature Request: publish connected bluetooth devices as sensor data

The Android app should be able to list all connected Bluetooth devices and if the list changes then update HA.

This would be very beneficial for location detection.

My personal primary use-case would be to detect if i’m driving my car. As soon as I start my car my phone pairs with it using bluetooth. If Zanzito was able to publish a list of connected bluetooth devices I could use that as a state in HASS.
