new props, tweaked older props

[UltimateCraneo]

NEW PROPS:

• gutted crucified 64alpha guy
• faceless, living crucified 64alpha guy
• flayed legs marine laying on floor
• face skin patchwork decoration UPDATED PROPS:
• better coloring on the hanged head tree, heads stand out way less and blend in better, also look rotten which is a bonus
• flayed torso marine has his legs tweaked so the model render's camo is less visible and thus feels more natural to the in-game design, also slight reflection on the helmeted variant
