Wiikey update

Finally the Wiikey website is back online and there is also a new update for the famous Wii drivechip. This time it has the version number 1.9s and fixes the issues with the original SSBB discs. Also it should no longer be possible to render the chip inoperable by using patched config discs. As another bonus there is a new config option to block system updates from gamediscs.
