Bug: 'noindex' tag lost after minification

[ram108]

Tag totally despearing:

<!--noindex-->Don't index this text.<!--/noindex-->

See wiki: https://en.wikipedia.org/wiki/Noindex

Confirmed. Because the given notation technically is a comment and Cachify removes comments using a simple RegEx, it is removed from the markup.

cachify/inc/cachify.class.php

Lines 1241 to 1251 in a3d7597

	$cleaned = preg_replace(
	array(
	'/<!--[^\[><](.*?)-->/s',
	'#(?ix)(?>[^\S ]\s*|\s{2,})(?=(?:(?:[^<]++|<(?!/?(?:' . $ignore_regex . ')\b))*+)(?:<(?>' . $ignore_regex . ')\b|\z))#',
	),
	array(
	'',
	' ',
	),
	$data
	);

The <noindex>Don't index this text.</noindex> notation is not affected.

Applies to a couple of other special-use comments as well. None of them really common though.

So the solution could be to disable the minification completely.

What about making this an option and split it up? "Minify HTML" and "Remove comments"?
