Sandstorms  

Adds sandstorms, which naturally occur on desert and arid shrubland maps. Functionally very similar to snow and rain, but breaks outdoors electronics rather than short-circuiting them.

Sandstorms will produce extremely windy weather and severely affect sight and movement of pawns on the map. They can appear as forced weather quests or incidents on maps that would normally not have sandstorms.

During sandstorms sand will slowly gather on the map, and sand being sand, it gets everywhere, even under roofed areas. Fallen sand will slowly be blown away by the wind on the map. Pawns will also clear fallen sand in any designated snow clearing zone, which now also functions as a sand clearing zone.

Even maps that would not naturally have sandstorms can still be affected by the sandstorm incident, which requires a nearby biome on the world map that would naturally support sandstorms.
