Art File Organization

Foxrun Art - naming conventions
Forest is the default, so those files won't have a suffix. They will be like this:
 * rock-pieces.psd
 * grass-pieces.psd
 * fling-platform.psd
 * bounce-platform.psd
 * extend-platform.psd
 * background.psd
 * decorations.psd
 * water-flows.psd
 * waterfall.psd
 * gloom.psd
 * intro-scene.psd
 * score-screen.psd
 * title-screen.psd

When a new tileset is made (example: winter) they will be like this:
 * rock-pieces_winter.psd
 * slopes_winter.psd
 * grass-pieces_winter.psd
 * fling-platform_winter.psd
 * bounce-platform_winter.psd
 * extend-platform_winter.psd
 * background_winter.psd
 * decorations_winter.psd
 * water-flows_winter.psd
 * waterfall_winter.psd
 * gloom_winter.psd
 * intro-scene_winter.psd
 * score-screen_winter.psd
 * title-screen_winter.psd
