v1.2.3.b2 - Part 2

## GENERAL
- Added a css_entity admin command to check whether an entity with a given index/handle exists (prints the designer name to chat or console).
- Added a TakeDamage post-hook (OnTakeDamagePost) alongside the existing pre-hook, so skills can now react after damage has actually been applied, not just before.
- Added CreateMolotovProjectile (new CMolotovProjectile_CreateFunc signature) and CreateTrackedChicken entity helpers.
- Added a weapon_mp7 → weapon_mp5sd fallback mapping.
- Added class for KillfeedIcons

## SKILL IMPROVEMENTS
- Aimbot:
  -- Only forces a headshot hitgroup once (skips if it's already a head or an invalid hitgroup), and now restores the original hitgroup value in the new post-damage hook instead of leaving it overwritten.
- Tripwire:
  -- Reduced the default wire width from 1.5 to 0.7.

## NEW SKILLS:
- Berserker: You deal more damage and move faster as your health gets lower.
- Blast Shot: Press Attack2 with the MP5 to fire an HE grenade.
- Demon Eye: You deal damage to every enemy you are looking at.
- Fire Rain: Throw a decoy to call down a rain of Molotovs.
- Flashlight: Click [css_useSkill] to turn the flashlight on or off; its light can blind enemies.
- Healing Chicken: Your chickens heal you while you are nearby.
- Jetkick: Select a player to jetkick - every shot they fire knocks them backwards until disabled.
- Last Gasp: After you die, you deal damage to the enemy who killed you.
- Take Ammo: Click [css_useSkill] to take the active weapon's magazine from a random enemy.
- Team Teleport: Press [css_useSkill] to teleport to the teammate you're looking at.
