2004-??-?? Michael Lauer <mickey@Vanille.de>
+ * Registered a signal handler. We're now trying to gracefully exit and emergency close capture files.
+ This should allow reproducing failures.
+ * Added sanity check for compile time vs. run time Wireless Extension versions.
* Added sanity check isPresent(interface) before starting the engine.
* Added a View submenu. Added actions to expand and collapse all items.
* Switched to a (hopefully) more reliable method reading from gpsd.
* 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 (speech).
* Added decloaking of cloaked ESSIDs (length != 0, but essid[0] == \0).

packet dissection framework... (unlikely)
