Bug 13826 - OPAC: Display RSS icon on list of recent comments

This patch adds RSS icon to OPAC page 'Recent comments'

To test:
1)
Enable display of 'Recent comments' in OPAC (Syspref OpacShowRecentComments)
2)
In OPAC, go to Home > Recent comments
3)
Verify that there is a link in the head part of the HTML source code (<link rel="alternate" type="application/rss+xml"....), but no RSS icon on the pate itself (like in search results).
4)
Apply patch
Result: Icon with link to RSS feed is displayed  next to title.
