Sort/normalize class tokens

[samme]

Like #4, this would help compression (and readability).

<a class="c a b"></a>
<a class="a b c"></a>

I'm concerned about this affecting class names containing templates such as this.

<a class="btn {{#if loading}}loading{{/if}}"></a>

The tokenization btn, {{#if, loading}}loading{{/if}} is clearly incorrect.

I'd also be interested in seeing the compression difference this makes. My suspicion is not much, but I'd be happy to be shown wrong.

I was imagining an option (default: false) since it's not suitable for every case.

I do wonder who write class names in random orders inside a HTML page to begin with.

OTOH, implementing this is probably simple enough, and gated by a flag makes it pretty safe as well.
