Move from (f *File).WriteString(...) to ioutil.WriteFile(...) to Fix a bug where WriteString fails because the file is closed before writing. (#393)

In a previous commit we started closing the file in createTempFile after having it returned to ensure that the os.Remove(...) would not result in error due to an open file handle. This caused WriteString to start failing.
