A few random tweaks

-Fix for bear traps: If a player is killed while inside a bear trap, they will no longer be able to become re-trapped in the closed trap after respawning.

-Changed hiking boots recipe to require a metal bracing. Updated texture to reflect the metal component, making them like steel-toed boots.

-Touched up a few textures: Slightly smoothed out reinforced sling texture and gave the grindstone base a unique inventory texture

-Gave Pigvil the ability to damage players when falling on them in pig form
