v0.18.0

html_prettify attribute improvements

Before this release changes like this occurred regularly:

-<a class="external link">
+<a class="link external">

-<a style="color: white; display: none">
+<a style="display:none;color:white">

This release sorts classes and formats style. This reduces the amount of diffs when the host only changes something like the order.
It also fits into the concept of 'pretty' HTML which this editor attempts.
