Replace newlines in a platform-independent way

[sualeh]

@nidi3 - great library! Unfortunately, I cannot build yet, or I would have submitted a patch.

I am reading a DOT file, and then using a JavaScript engine to generate a graph image. My code is roughly

Graphviz.useEngine(new GraphvizV8Engine(), new GraphvizJdkEngine());
Graphviz.fromFile(dotFile).render(format).toFile(outputFile);

If the DOT file has newlines, this will fail. Please could you make the following modification on my behalf?
In guru.nidi.graphviz.engine.AbstractJsGraphvizEngine, replace newlines in a platform-independent way:

protected String jsEscape(String js) {
		return js.replace("\\R", " ").replace("\\", "\\\\").replace("'", "\\'");
}
