~~~ block does not work in HTML codegen

[Hendrik-H]

My description contains a ~~~ block that renders fine in the swagger editor. When I use the code gen command with HTML as the target language no code block is being created but the ~~~ are displayed in the text. Furthermore all the line breaks are shown as \n.
I'm using http://repo1.maven.org/maven2/io/swagger/swagger-codegen-cli/2.1.6/swagger-codegen-cli-2.1.6.jar

@Hendrik-H I think that's because the HTML doc does not support markdown syntax at the moment.

If you've time, I wonder if you can help contribute the enhancement to support markdown.
