Allows you to insert any of the JSPWikiPlugins directly into the template.
<wiki:Plugin plugin="<plugin class>" args="<argument string>" />
<wiki:Plugin plugin="Counter" args="name='foo'" />
Inserts the CounterPlugin, with its name set to 'foo'.
This tag could be removed or deprecated, it is rarely used and if so the Translate tag:
<wiki:Translate>[{Counter name='foo'}]</wiki:Translate>
is sufficient and directly corresponding to the wiki formatting rules.
