Update to v0.4

After a rather long hiatus, and spending a lot of time trying to create my own products for a grocery store, I finally pushed the next version of the game.  It is also rather likely this will be the last push so I can move onto other projects.  I flushed out the right side of the store, providing 17 more aisles of products, which I believe adds more than 200 products to the game.  I made it so that you now get 2 seconds per item instead of just 1, since you run around the store more and it takes more time to get the requested products.  I also spent a lot of time adjusting the lighting settings in the game, and finally pushed something that was "good-enough".  I hope you enjoy the game, as I am officially calling this project complete.
