Add replacement for List.all

[jfmengels]

This makes List.all quite a lot faster. The problem is the original uses this implementation:

var $elm$core$List$all = F2(
	function (isOkay, list) {
		return !A2(
			$elm$core$List$any,
			A2($elm$core$Basics$composeL, $elm$core$Basics$not, isOkay),
			list);
	});

The composeL (or << in Elm) is actually not very performant (benchmark, results). We could also make the same change by transforming composeL/composeR calls by anonymous functions, but that's more work. I do plan to add that, at which point we can probably remove this replacement (EDIT: done in #73).

I benchmarked the change. This is after compilation with elm-optimize-level-2 v0.2.3:

Results on Chrome:

Results on Firefox:

I don't have a Safari readily available, but I'll try to get results later (work computer is a Mac, so I can get them later).

I found a newer version, 4x faster than what I proposed earlier.

This is basically a re-implementation of the function, written almost just like List.any and that doesn't defer to it.
