Panic Attack Fix Pack

A collection of fixes I made for the Panic Attack post Christmas 2014. These fixes include;

• A new killicon for the Panic Attack
• Fixed crit-glow .vmt
• Fixed lod1 being the same mesh as lod0
• Fixed floating shell on Pyro
• Fixed shells not being loaded in first person
• Fixed shell ejection port not moving in first person on Engineer

This will not be compatible with any other killicon fixes that modify d_images_v3 or dneg_images_v3, so probably most
