Fix text/newline handling with QSaveFile.

Browse Source 
Fixes #309.

We use io.TextIOWrapper which already handles newline converting, so we
shouldn't open the QSaveFile with QIODevice.Text in the mode, as this lead to
double-converting newlines, which in turn produced this error message on
Windows.
