Rewolf: Preparing initial work
Effects: Added Gib-Human effect
CBaseEntity: Make sure things that are hidden can't be damaged by default. E.g. func_breakables that are hidden
func_door_rotating: Minor tweak saving us a few bytes
item_food/sodacan: Make bounding box bigger, fix classname check to apply to "player", not "Player" (TW leftover)
Damage_Radius: Fix how damage radius checks for brush based entities.
Scientist Hunt specific stuff:
- impulse 103 test cvar added to destroy everything around the map
- scientists can be gibbed
- scientists scream when falling
- new cvar sh_scialert that spawn scientists alerted
- new cvar sh_scispeed that is mirrored from the original mod
- new cvar sh_scimax that will limit the amount of scientists spawned by the shdata system
- new cvar sh_sciyaw that will randomize the spawn yaw angle when there's no other specified
