Huzzah, a new release!

It’s taken longer than I wanted, but I have finally finished Tetzle 2.0! There are some big visual changes from the previous version (drop shadows, piece bevels, adjustable background color…), and some smaller ones like a brand new dialog for choosing games. I didn’t like the disconnect between the new and open game dialogs, so I merged them into a tabbed dialog. Also, I rewrote the entire graphics layer, along with the code to detect which pieces to attach and which pieces to push when you drop a piece. Finally, thanks go to Sergiy Gavrylov for adding a Ukrainian translation. I hope you enjoy this release as much as I did making it!
