Fix multiple chunk generation in Scratch-SAMPLE-ONLY repo

[GK503]

If you look at CreateTiles() function in App.java their is a comment that says that says
// FIX THE ERROR
and that line of code underneath that is the code that controls the positions of each tile (each tile is a JLabel). You would need to modify that line of code that includes that mathematics so that each 9*9 chunk is generated next to each other.
