Updated Weapons

Hey, guys! I finished work on updating weapon's visuals, and also added a couple of modifications and visual deformation to all weapons. I decided not to make a large number of mods yet, but to finish this task earlier and move on to the next ones, so this devlog won't have many changes.

　　 Models

• Updated the Hammer model and modifications for it;

• Updated the Knife model and added modifications for it;

• Updated the Club model and added modifications for it;

• Updated the Sword model and added modifications for it;

　　 Other Changes

• Added the reliability/durability parameter. Affects the damage rate of weapons/armor;

• Fixed: Barter reduced the cost of mods and equipment repairs too much;

• Updated axe and hammer wood textures;
