  Fixed the QML browser built into the QML viewer
  Make configure.exe fail for declarative if no script support
  Add QWidget::update() test.
  Add license headers
  Import static contents tests from old manualtests
  Fix Build Failure for Maemo 5 Debug Build
  Add ability to read last mod.time for zip entry.
  Avoid asserting when index passed to QZipReader::entryInfoAt is out of boundaries
  Add isValid() method to QZipReader::FileInfo.
  Add `QIODevice* device() const` public method to QZip classes.
  Rebuild configure.exe (again enable QtDeclarative module by default)
