Discussion feature enabled for the wiki

Hi all,
  I've enabled the discussion feature for the wiki. Logged-on users
can discuss pages using the "Discussion" link in the edit menu.
Discussion is kept in a separate subpage, and is not shown in the main page.
See http://wiki.squid-cache.org/HelpOnConfiguration/SupplementationPage

I've also fixed a bug in the text template which prevented comments
from working properly.
Please see http://wiki.squid-cache.org/HelpOnComments for details.
