New Sly Cooper Downloads

I just discovered that the soundboard downloads on the Downloads page weren't functional (and probably haven't been ever since we changed domains from SlyCooperNet.weebly.com to SlyCooperNet.com), so I fixed the links, and the awesome soundboards from Sly Cooper and The Thievius Raccoonus can now be downloaded once more! I also added the Sucker Punch art pack to the downloads page (which I had to split up into two parts due to size restrictions), and the last surviving issue of Cooper Capers, the discontinued online Sly Cooper Magazine.
