QMLTest: Fix output of file names, make output more verbose.

- Check command line arguments thoroughly.
- Change all QuickTestResult functions taking file names to
  accept QUrls and format them using QUrl::toLocalFile() in case
  of local file names in order to display Windows drive
  letters correctly.
- Introduce a template function (for QDeclarativeView, QQuickView)
  that dumps out all available information when compilation goes
  wrong.
- Skip 'Debug', 'Release' folders for Windows builds.
