- Adjusted the explosive damage of landmines already present on the maps (against the player)

- Added 2560x1600 resolution support

- To reduce the amount of inventory management work, I made it so that under the following circumstances, the game will try to put the items back to player's backpack; and if anything can't fit, they'll be dropped on the ground with a warning message:

1. When closing the trading menu while some items are in the "sell" grid
2. When closing the serum crafting/cooking menu while some ingredients are in the "ingredients" grid, or if a serum is in the "product" box
3. When closing the workbench menu while any items are in the input/output grid
4. When closing the farming menu while any seed/fertilizer are in the boxes
