Don't return Windows newlines through the PDF GetSelectedText JS API

Don't return Windows newlines through the PDF GetSelectedText JS API

Previously we used to return Windows newlines through the GetSelectedText JS
API but this is fairly unexpected in JS (for example the window.getSelection()
doesn't seem to return Windows newlines on Windows). Instead just return unix
newline characters.
