Wt

README.text in wt/examples/wtwithqt/lib mentions that a QApplication object is needed if Qt event loop is required. However QCoreApplication is enough and should be preferred for most of the applications since QApplication pulls in QtGui which most likely won't be necessary in a Wt application.

The hello.C file of the example application in wt/examples/wtwithqt #includes and instantiates a QApplication instance in main() if the the relevant lines are uncommented. These should be changed to QCoreApplication.
