Update 0.8.54

Fixed a critical bug on the Old Path level, when the level did not start from the beginning, but almost from the end.
White smooth plates of enemies that were immune to plasma no longer show 0 damage when hit by plasma, but reflect plasma.
The view of the character without weapons is now a little more centered.
Minor graphics changes at the battlefield/building area level.
The epicenter of the colossus' step now kills, not just knocks the player down.
Improved materials of metals and marble as part of the preparation of graphics for the Olympus.
Small code optimization.
