在fckeditor for wordpress样式菜单中使用wp-syntax插件

wp-syntax是wp的语法高亮插件，支持包括了c、python、sql、shell、diff等等在内的大多数程序语法格式，它使用特殊的xml语句对字符串进行对应程序语言的格式化。可以在这里下载。

fckeditor for wordpress是在wordpress上使用的类微软office界面的所见即所得编辑器插件，同时可以通过修改代码定制自己的工具栏。可以在这里下载。

第一步：通过修改fckeditor的样式表文件，加入wp-syntax支持的语法格式。

第二步、由于fckeditor默认把html的特殊字符进行了转义，而wp-syntax不处理这些转义过的html转义符。所以需要把转义符还原为原始的字符串：

$i = count($wp_syntax_matches);
$wp_syntax_matches[$i] = $match;

效果图：

TODO：可能还需要在syntax.php的wp_syntax_after_filter函数中重新把没有按语法格式化的特殊字符替换转义符，但没作也没发现什么问题，估计这块wordpress会自动替换，就不作这个工作了。
