Weather
Weather now happens across Ficterra
Rain, Snow. Fog and Dust Storms will now show up
Biomes dictate what type of weather appears
Clouds are now part of the new weather system
Removed old 'Acid Rain' weather
The 'weather' dev command now toggles the weather for the world
Misc
Beeps in the main menu are now correctly affected by the Sfx audio setting
Weather noises are now controlled by the Sfx audio settings
Minor performance improvements
Removed old 'SEGI' system for lighting. It controlled the 'Medium' and 'High' deferred rendering lighting. This didn't increase the graphical quality much, but was a massive performance hit for our game
'Medium' and 'High' deferred rendering now use the custom lighting used by Low but with a higher degree of accuracy
