Subject: [PATCH] Sort tags for consistent display
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This ensures that the tag list will be consistent rather
than based on the browser’s internal hash implementation. It
also allows a custom override function to be configured when
simple alphabetic sorting is not sufficient.

Closes #342
Closes #505
