Example code syntax highlighting bug

In the https://cfdocs.org/application-cfc page under the "Relative mappings - Advanced Example" example, the prettyprint code has incorrect syntax highlighting. This appears to be due to it erroneously thinking that quotes are escaped with \.

code-prettify doesn't support ColdFusion. Maybe we should use another highlighter…
