Quick Fix v0.0.9b

Eggs now drop through the three farm plots on the old farm.
Added a setting to change the mouse lock mode, which by default will lock the mouse cursor only if the game is in fullscreen mode (Settings → Video).
Deleting sand no longer gives trash back, as it could be abused to generate an infinite number of trash bags and coins.
Added a toggle crouch option (Settings → Gameplay).
Fixed the collision of planted fruit trees, which could cause players to get stuck.
Fixed an Honesty Box exploit that allowed players to duplicate items.
Fixed a bug which allowed your character to uncrouch even if it had something above its head.
Corrected the crafting recipe for Iron Arrows.
Added a check which should trigger the Stone Tier Achievement for players who unlocked this tier in the demo and then moved to the full game.
