Jan Stürtz 08eb5b42eb Fix progress output on Windows
The windows cmd shell is not aware of ANSI escape sequences and
does print them uninterpreted to the console. This is ugly.
Added a function to generate platform specific string for the escape sequence. On Windows this will be 79 white spaces with
a trailing \r.
