[SDL] Problems with the libSDL.org RSS feed

[Christophe Cavalaria]

My RSS agregator might be a little pushy about it, but the libSDL.org RSS
feed isn't valid XML and thus it refuses to display it now.

The problem is because of a single & that isn't escape with & :

Problème lors de l'analyse du XML
problème grave lors de l'analyse : letter is expected à la ligne 17, colonne
31
<title>DXX-Rebirth (Descent 1&2)</title>
                              ^

Damn you XML!
