Added logic for ledge grabbing with and without a supporting wall underneath. Animations play correctly with transitional animation and hanging idle appropriate per ledge type.
Added climbing up from hanging state on a ledge, and while it executes as directed, it looks a bit derpy. Will require some tweaking.
Entering and exiting crouch/crawl state works and animates properly.
Updated other animation transitions for better behavior.
Added muzzle flash to pistol.
Added impact effect to bullet.
Added radiant light source effect to sword when equipped.
