StringEscapeUtils.escapeJavaScript

• Escapes the characters in a String using JavaScript String rules.
• Escapes any values it finds into their JavaScript String form. Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)
• So a tab becomes the characters '\\' and 't'.
• The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote must be escaped.
