Power Armor Change:

Tweak the BN power armor. (Previously Port power armor improvements from DDA to BN.)

Rename several items still using the old term power armor to use the newer term combat exoskeleton.
-And rename the salvaged power armor helmet to salvaged environmental combat helmet.

Add Swim Goggles flag to helmets.

Add Partial Deaf flag to helmets while active.
-This allows the suit to be used by non-cyborgs without going deaf.

Fix light/medium/heavy exoskeletons and helmets being mis-categorized as tools instead of clothing.
