Added language support for Romanian, Swedish, Finnish, Polish and Hungarian.

Added language support for Thai, Norwegian and Simplified Chinese.

Now when you start the game for the first time, instead of having just one screen, there are five screens in succession that better explain how the pieces fit together.

You can now use the mouse to move the puzzle pieces.

Controls fixed and added key rebinding.

If you fail to complete the first level (the one unlocked from the level selection menu), now the second time you fail to solve the puzzle a popup window will appear asking if you want to repeat the tutorial level.
This is to avoid getting stuck at the first puzzle of the game.
