markdown: Don't link URLs in code blocks.

When passing a content throught the `markdown_to_bb` function
to convert any markdown in the content, any recognized URLs in the
content would be converted to BBCode links as a post processing step
after the main conversion.

After commit a1ccacb825edac6ae36e5db4f62ebfe7aeaebe9f this did no longer
consider content within code blocks, and would thus convert them as
to BBCode links.

Example: The following content

	[code]
	example url: https://example.com
	[/code]

Would be converted to

	[code]
	example url: [url=https://example.com]https://example.com[/url]
	[/code]

Prior to commit a1ccacb825edac6ae36e5db4f62ebfe7aeaebe9f, code blocks
would be protected, so this would not happen.

This patch removes the post processing step for converting plain URLs to
links completely from this routine. This functionality is in any case
covered in the actual BBCode parser where it belongs.

This will have some other side effects as well, such as images and links
created using Markdown, will not be converted to [zmg] or [zrl] tags
where that would be done automatically before. If you intend to use a
[zrl] or [zmg] tag, you now need to do so explicitly.
