No more Java Web Start

[Jacob__mybb_import1]

One of my goals is to make it so almost anyone can play Buildism with little difficulty. We were using Java Web Start, which was causing a few users to have issues, even though they had Java installed. So, Buildism now uses Java applets only! They are older and well-supported, so this should eliminate all of the old problems. It will also make some cool features possible in the future, like allowing you to embed your game in your own website!

If you find any bugs in the update, please let me know.
