add hack-a-round for language specified markdown code blocks

When language is specified in a markdown code block such as: ```` ```c printf("Hello, world!\n"); ``` ```` is used, the resulting HTML as produced by `pandoc(1)` combined with our revised `ioccc.css` is not intent the code block well. A temporary "_hack-a-round_" is to turn the "markdown code language specifier" into an HTML comment. For example: ```` ``` printf("Hello, world!\n"); ``` ```` This commits turns off existing markdown code language specifiers for now, while preserving our ability to restore them in the future when a better "_hack-a-round_" to the "markdown code language specifier" problem is found. The HTML impact if this "_hack-a-round_" is to produce HTML that looks like this: ``` <pre class=""><code> .. </code></pre> ``` We might be able to create a complex set of classes for each markdown code language (there won't be very many) in `ioccc.css`, or we might find a more general CSS (or maybe `pandoc(1)`?) solution. For now, this hack-a-round will have to do.
