Revert "news.php and pages.php had calls for code block 1+ but default is code block 0. Must have been that way for longer I guess."

This reverts commit da0f977f5efe54dfc20042f4874b16b56a516424.
fix #280

This and the before reversion set the standard for codepages to start at
one. The only exception to this will be if you already have a codeblock
0, then you will get to use it. (Or better yet, move the contents to
some other codeblock >= 1)
