[PATCH] Tags template cleanup
From: Edouard Gomez <edouard.gomez@gmail.com>
Tags template cleanup
This page lists all tags, thus using divs doesn't structure well
the information. Better use a list (ul). Each tag becomes a li
element. The li element also carries the parity information.
As font style tags are highly deprecated in newer HTML variants
get rid of the tt element, relaced by a simple span that gets
a CSS class that mimics tt default style (monospaced text)
Added CSS classes required to match old style.
