Display stations sending out named ProbeRequests.

Wellenreiter II reaches a critical point in its lifetime, i.e.
the scanlist and wellenreiter classes are the mainly still as they
were during the early prototype phrase. It's time to rewrite the major
UI core and start with giving it something like a design (D'Oh!)...

+        * Added parsing of named ProbeRequests. Display only-probed-yet SSIDs in a different network color.
         * Rewrote the simple actions on new {Network, Client, Station}. Besides playing a sound or
           blinking a LED, a user customizable script can now be executed, if something has been
-          detected. This opens up many possibilities, i.e. a qcop to qpegps or exec'ing Flite.
+          detected. This opens up many possibilities, i.e. a qcop to qpegps or exec'ing flite (speech).
         * Added decloaking of cloaked ESSIDs (length != 0, but essid[0] == \0)
         * Hided the 'Parse' Tab in the configuration window. Not functional now and may come later
-        * Added parsing of control frames. Display stations sending them SSID "???" for now.
+        * Added parsing of control frames. Display stations sending them SSID "<unknown>" for now.
         * Added command line option "-nocheck" to skip non-root and dhcp tests
         * Improved the speed reading the manufacturer list
         * GPS coordinates are now presented in the DMS (as opposed to decimal) format
 
         2003-12-18      Michael Lauer   <mickey@Vanille.de>
 
         * Released as Version 1.0.2 (Development Snapshot)
         * Added automatic uploading of capture files to "The Capture Dump" site at
           http://www.Vanille.de/projects/capturedump.spy
         * Initial reading of the manufacturer database happens now in background
         * Removed deprecated setMonitorMode() API ==> Use setMode( "monitor" ) now.
           The monitor mode now tries to use the standard IW_MODE_MONITOR first. If that
           doesn't work, it falls back to using the proprietary iwpriv commands

         * Released as Version 1.0.1 (Development Snapshot)
         * Fixed ARP decoding for wired networks.
           Interestingly, 802.11 encapsulates these in IP packets, while wired ethernet just tags the type_of_protocol.
         * Added reading GPS data from a gps daemon.
         * Started preparations for utilizing Wellenreiter II in wired networks.
         * Implemented persistant configuration interface and retriggerable auto detection.
         * Added QCOP interface for talking to opie-networksettings.
         * Added parsing of DHCP packets and detecting DHCP servers.
