/*
* TODO:
*
* HIGH:
*
* - check why return NULL from method call triggers cancel error
* after timeout.
* - find out why alias == address in _bluez_request_pincode_cb
* - more complete agent support (handle requests from devices)
* - handle device-disappeared events
* - icon with device state (trusted, connected, paired)
*
* LOW:
*
* - configure (probably module) timeout to trigger automatic rescan.
* - gadgets to show different adapters (see mixer module configuration)
* - module to choose the default adapter (see mixer module configuration)
* - icon with device class
