- Fixed Python Barney lua error
- The lifespan of the NPC while the NPC has one minute to live is now increases a bit, when the NPC receives a heal (Half of the gotten HP)

- Another fix to scientist dialogue anims...

Fixes to the "1 minute left to live" system for Barney's/Otis's:
- Replaced "Barney" & "Otis" with self:GetName() to dynamically use NPC's name.
- Countdown pauses when NPC stops following the player and resumes when following again,to avoid NPC unnecessary dying.
- Fixed negative countdown values by stopping the timer correctly.
- Added checks to ensure the entity that is Otis/Barney is following is valid and is a player before updating countdown.
- Properly stops the timer if the NPC is no longer bleeding or is invalid.

Please report other bugs, if you see one.

- Fixed scientist dialogue animation being not interruptible

- Finally fixed muzzleflash pos being misplaced a bit.

- Again...

- Fixed NULL entity error for RPG NPCs

- Added homing mode for the RPGs! (Togglable in Half-Life 1->Toggle RPG homing mode)
- If homing mode is disabled, the rocket will still never miss the target, despite being tiny.

- Fixed injured idle animation being replaced by guarding one, while guarding.

- Fixed RPG Barney, HGrunt & Otis accuracy, especially for tiny NPC's like headcrabs, so the rocket won't go up, instead straight to the enemy.
