With the new routes, all pages are not all at the same folder level anymore
(e.g. /shaare and /shaare/123), so we can't just use './' everywhere.
The most consistent way to handle this is to prefix all path with the proper variable,
and handle the actual path in controllers.
* The tag list can be sort alphabetically or by most used tag
* Edit/Delete are perform using AJAX, or fallback to 'do=changetag' page
* New features aren't backported to vintage theme
