Added population of device info from BLE2 data source, and added auto-reconnect if the device disconnects. Note, if it disconnects for too long, the Pinetime goes to sleep and you need to press the button to re-enable it to clear the FAULT condition. This needs a PineTime firmware change to fix it.
