This patch adds scanning the "network neighbourhood" in networksettings-wlan

(powered by the Wellenreiter II scanning engine found in libopienet2).
Detected networks are put in a list and you can select parameters by clicking
on an entry in the list. See http://opie.net.wox.org/images/wlanplugin.png

Two inherent drawbacks:
1.) networksettingsplugin-wlan now needs libopienet2. Well, my library work pays
off. If you like to rewrite the stuff so that libopienet2 is not needed, then just
go ahead ;)
2.) Scanning won't work on linux distributions without patched monitor mode drivers.

I think we can live with these two "issues". Feel free to revert, if you don't like
my work :D
