The clock "in the tray" was showing old time for a while.

Committed on 07/10/2011 at 18:50. Pushed by afiestas into branch 'master'. Replaced AgentListener (QThread) by delayed DBus messages This thread has been causing many crashes for some people, and as far as I remember all the backtraces show weird things not really within BlueDevilcode, and of course none of the BlueDevil developers has been able to reproduce the bug. So the best/easy/simpler way of fixing this is by removing the Thread which shouldn't be there in the first place.
