QML examples not launching on Windows platform.

While the QML examples work fine when loaded through the QML viewer, however, the executable launching version does not work.

This is due to a problem in the path for the qml file in qmlres.h. The "QCoreApplication::applicationFilePath();" function returns directory separators which are incompatible with a later call to QDir::separator();

Additionally, the current version doesn't take into account the ".exe" extension on Windows files.
