TFCGenViewer 1.4.1

Add toggleable tooltip when hovering over the preview
Color(Gradient)Definitions now have the ability to define a key for the tooltip (multiple in the case of gradients)
Biomes and Rocks ColorDefinitions can now be disabled, preventing them from being added to the color key
Fix in-world previews showing the coords the preview is centered on when the server has disabled coordinate viewing
Adjust Temperature visualizer range to be -20 to 30 °C to better reflect the temperature ranges available in default TFC
