RSS bug fix : special character on title and contact node recommendation

With 8a18331 commit, I've corrected the bug of special character on title of post. For exemple, a title with "é" look like :
Chrome :
![error_rss_chrome](https://f.cloud.github.com/assets/5948003/2369106/c4f87404-a7ce-11e3-87e1-4a98724acd40.png)
Firefox :

I checked the code, and have found the probleme on function htmlentities().
