Minify less CSS

[Joey Smith]

I feel like this code is just creating far more problems than it fixes; we don't keep good track of the original state, and the times where the specific syntax matters has grown larger than the cases where it doesn't. My thought is to remove this entire block from the CSS minifier code:

	// Replace 0(px,em,%) with 0. css = css.replaceAll("(?i)(^|[^.0-9])(?:0?\\.)?0(?:px|em|%|in|cm|mm|pc|pt|ex|deg|g?rad|m?s|k?hz)", "$10");
	// Replace x.0(px,em,%) with x(px,em,%).
	css = css.replaceAll("([0-9])\\.0(px|em|%|in|cm|mm|pc|pt|ex|deg|g?rad|m?s|k?hz| |;)", "$1$2");
	// Replace 0 0 0 0; with 0.
	css = css.replaceAll(":0 0 0 0(;|})", ":0$1");
	css = css.replaceAll(":0 0 0(;|})", ":0$1");
	css = css.replaceAll(":0 0(;|})", ":0$1");

Sure, it will mean we're slightly less agressive about how we minify CSS; however, I think it will also mean we BREAK less CSS. Any thoughts, concerns, etc. are hereby solicited.
