QtTestLib update

[Harald Fernengel]

Hi,

just updated the QtTestLib with the recent snapshot. I believe all requested 
features should be fixed (basic exception catching, more verbose XML, return 
value indicating amount of failed tests).

If everything goes well, QtTestLib should appear in the Qt 4.1 snapshots (as 
part of the default Qt installation) soon, so the question about where to 
fork it should be resolved :)
