Better Search for Colored Grids

Making the colored grids was definitley not an easy task. When I was done I knew it was too slow. After some thought on ways to make it faster I decided to tackle it one more time. Now the grid takes an image and crops it into smaller blocks. Each of these blocks becomes a search area. So when items are dropped on the board or deleted from a colored grid it's 10 times faster. And coloring the image is also faster.
