fine-tuned the image search function a bit, added game control buttons (start changes to quit and reset, quit changes back to start, etc.), and prevents user from changing puzzle image (by clicking on a search result) after the game has started; started on actual game code - just beginning to figure out how to split the image into puzzle tiles, make an invisible grid on the game board to snap tiles to, etc.
