Title: Created script to merge all item images into one PNG file and create CSS file to access individual images

There is probably room for improvement here, especially if you want to apply this to more than just the item images; I can definitely make this more generic. This script iterates over all the images in the item directory, builds the merged png file and creates the CSS file as requested.
