Tweaks to ore nodes: -Increased brightness to stand out more -Sulfur nodes show a more distinct yellow hue -Metal nodes show more oxydization -Stone nodes are overall more desaturated, more grey to stand out against other nodes -Added Gibs models for every node picking stage (to be implemented later @helk) -Snow biome nodes should be more visible and easier to differentiate -Nodes are overall slightly smaller -Cave ores are much smaller
