Neutrino-GUI - DBoxII-Project

Kommentar:
Diese GUI wurde von Grund auf neu programmiert und sollte nun vom
Aufbau und auch den Ausbaumoeglichkeiten gut aussehen. Neutrino basiert
auf der Client-Server Idee, diese GUI ist also von der direkten DBox-
Steuerung getrennt. Diese wird dann von Daemons uebernommen.
