v1.0.2 - Combat and Item Glow Update

A. Balance

1. make game difficulty affect object glow-frequency and glow-distance (the distance at which objects start glowing)
   • at easy difficulty, items will glow more frequently and at a greater distance
2. add mini-stun mechanic
   • upon receiving damage, zombies will be mini-stunned
   • the duration of the stun depends on:
     • i. weapon type (heavy weapons add more stun time)
     • ii. enemy type (fallen are stunned for less time than others)
     • iii. headshot/sneak-attack
3. improve fast zombie approach&attack AI

B. Other

1. add blood pools to recently killed zombies
2. add more zombie hit reaction animations
3. add camera shakes and distinct gore sounds to melee head-shots, sneak attacks
4. add unique thumbnails for unique items
