Buttons Skin

If you want to edit the colors, you'll have to do this manually, unless someone can help me with "dynamic" variables (where you take the color of the top bit, and make it darker for the bottom bit)
The images for the buttons are full-size, because this was easier to position - so if you want to make the images as big, make sure they're 32x32, or 16x16 (big and small), and centered.
