+Add new applet solidnotifier wich will in future show new devices.I put it directly here because it was a default applet wich will be loaded on start. Send me email if problem. +Modify solidnotifierengine in order to connect it with solid.Just connect signal, no filter and so +Problem in solidnotifier applet->don't find the solidnotifier engine.See it later. svn path=/trunk/KDE/kdebase/workspace/libs/plasma/; revision=684582
