[SUBMISSION] and [UPDATE] Zombie Scientist pack

This is both an update of all the existing zombie/former scientists already in the repo, as well as a submission of 2 new ones.
I made this primarily to have them all in one single pk3, and to get rid of duplicate actors and assets.
I had Tsran's sprites of a freeze-rifle wielding scientist lying around so I decided to include him in the pack as well. Then I noticed a lack of ranged options for the female scientists so I made one with a pistol.

Here's an overview of the submission/update:

• new: ZombieScientistFreeze
• new: ZombieScientistPistol
• streamlined all classnames by weapon:
      - ZombieScientistAxe
      - ZombieScientistCleaver
      - ZombieScientistCrowbar
      - ZombieScientistHalon
      - ZombieScientistHammer
      - ZombieScientistKnife
      - ZombieScientistPlasma
      - ZombieScientistSyringe
      - ZombieScientistUzi
      - ZombieScientistWrench    
• ZombieScientistHalon overhauled, now also drops his FireExtinguisher which explodes when damaged
• replaced male and female voice sounds, streamlined all sound names
• adjusted sprite offsets, some minor edits to a few sprites
• removed unused and duplicate assets
• fixed incorrect obituaries and missing decals
• updated zscript, replaced deprecated functions
• adjusted all zombie stats to be more in line with each other
