Fix several issues with building resists.
Note : Following changes do not affect current gameplay at all. This is a bugfix.
All buildings except for Engineer radar/camera
APBulletResist -> 1
BioResist ->1
All buildings except for wall/turret/engineer camera&radar
ExplosiveBulletResist 0.8->0.78
Wall
ExplosiveBulletResist 0.94->1
Currently, DUMG does not hurt buildings (except for turrets), HEMG does not hurt walls, because <1 damage is being truncated, hittick is however still displayed under these circumstances.
This fix is so hittick will no longer be displayed under these circumstances.
We also don't want DUMG to hurt buildings & HEMG to hurt walls.
