Ruby script to download PS3 updates

[Gogyimogyi]

I wanted to download the updates for my games and since I use Linux I created the following simple ruby script to make it easier.

First it asks the id of the game, then downloads the XML and displays the available updates. You can choose a version or all to download. You need ruby and wget to use it. I hope someone will find it useful.

Just a small fix in the target folder's name.
