Allow renaming QTemporaryFiles on windows
Allow renaming QTemporaryFiles on windows

Changed the fallback implementation to use 'this' instead of a new
QFile. This allows a QTemporaryFile to be block-copied to the
destination and the source to be removed (QTemporaryFile is special
because it isn't really closed).
