Is your feature request related to a problem? Please describe.
Unsorted HTML attributes are annoying to look through but even more annoying to fix. It would be neat if HTMLHint could automatically order attribute tags.

Describe the solution you'd like
When linted, HTML attributes should be sorted in some (ideally configurable) order. Like so:

<div id="one" class="red"></div>
<div class="blue" id="two"></div>

Should become:

<div id="one" class="red"></div>
<div id="two" class="blue"></div>

Describe alternatives you've considered

Additional context
I don't exactly agree with this sort order but it illustrates the point:
