Command line option --allow should use shared directory

[tresf]

When deploying in a headless environment, the --allow command line flag currently defaults to the user's directory, but it should instead default to the shared directory.

	public static boolean printLineToFile(String fileName, String message) {
	File file = getFile(fileName, true);

Currently, printLineToFile doesn't have an override to specify that it's a shared file. It calls getFile(..., true), which defaults to a local file, not a shared file.
