[stringtemplate-interest] ST4: simple write to file method.

[Udo Borkowski]

I would also add a charset/encoding parameter to the most general write method:

> 	public int write(File outputFile,
> 					 STErrorListener listener,
> 					 Locale locale,
> 					 int lineWidth,
> 					 String charsetName)…

and pass this to the OutputStreamWriter constructor

> 			OutputStreamWriter osw = new OutputStreamWriter(fos, charsetName);


The other write methods could then pass an "UTF-8", e.g.

> 	public int write(File outputFile, STErrorListener listener, int lineWidth)
> 		throws IOException
> 	{
> 		return write(outputFile, listener, Locale.getDefault(), lineWidth, "UTF-8");
> 	}
