KunenaTemplate->addScript never finds a "-min" version

Adding proper path to the filecheck.

It should also be considered to change JFactory::getDocument ()->addScript() to JHTML::Script() to allow overriding using the site template. See http://www.babdev.com/blog/139-use-the-media-folder-allow-overridable-media for this

In my case container is used as an id in my template which caused issues in IE.
