Dynamic Market 1.2.0

1.2.0.0:
- get an in-game notification when a good you have in stock rises notably in price
- show an item's storage locations at the press of a button, including map tagging for the storage location and the best sell point
- the "Sale value" column now shows stock x current price instead of just the price difference to base price
- goods in trailers/implements and production building outputs now count towards the shown stock
- manure, liquid manure and digestate are now tracked as sellable animal products
- unclassified but genuinely sellable goods now get their own "Map-specific" price group instead of being ignored
- market prices were recalculated every 5 seconds even when the period had not changed
- "Normal" price-base mode now keeps the original seasonal curve instead of flattening it
- group names and market notices now consistently use the shipped translations
- crop farming and other merged categories had lost their seasonal price influence
- Only actually unloadable and sellable products are now shown for production buildings, animal barns and attached implements
- sales pressure at selling stations: selling large quantities at once temporarily lowers the price there, which then recovers over time. Two new settings control the threshold and the price drop per step
- Simplified how the mod's menu tab registers itself, to be more robust for gamepad/controller navigation
