* sane size on the ExtenderTask
* don't use an arrow for the ExtenderTask; it's a wee bit non-descript, wasn't following the orientation. so now we try and determine (through a bit of a silly hack with Solid ;) whether this is a laptop or not and show an appropriate computer icon
* really delete it when all the jobs are gone

it seems that now all the parts of the system tray work well and other than the XEmbed-vs-QGraphicsView struggle, the likes of which have not been since Gamera-vs-Mothra, it works and looks better than any systray implementation we've had =)
