Update 0.9.56

Archery has been improved. Arrow speed has been increased (5x). The aim does not turn off after each shot. Shooting sounds have been improved, and a “satisfaction” sound has been added when a shot hits the enemy.
The highlight for arrows indicating they can be picked up has been changed. It is now a subtle blue glow instead of a green marker (which slightly ruined the aesthetics).
Small video clips have been added to the Olympic rifle upgrades window.
The appearance of the smelter has been changed.
