* examples/python/NetworkManager.py:
added convience functions has_wired_device and has_wireless_device
* examples/python/systray/network_tray.py:
cleaned up a bunch of cruft, added support for listing wireless
networks just like the real applet. This is probably all I'm
going to work on this applet from now on.
TODO: add support for actually changing networks and devices
