"""Displays bluetooth status (Bluez). Left mouse click launches manager app,
right click toggles bluetooth. Needs dbus-send to toggle bluetooth state.
Parameters:
* bluetooth.device : the device to read state from (default is hci0)
* bluetooth.manager : application to launch on click (blueman-manager)
* bluetooth.dbus_destination : dbus destination (defaults to org.blueman.Mechanism)
* bluetooth.dbus_destination_path : dbus destination path (defaults to /)
* bluetooth.right_click_popup : use popup menu when right-clicked (defaults to True)
