Port power armor improvements from DDA to BN.

Change the materials to "hardsteel", "ceramic", "kevlar_rigid".
-Except for the salvaged set, which remain just steel.

Set the storage of suits to 20 L to simulate the equipment pockets added in DDA.
-BN does not support the same item being both push-to-activate and a holster.

Set power draw to 0.
-They still consume 3 kJ per second as BN depletes the UPS via the source code.

Add Swim Goggles flag to helmets.
-But not the salvaged one.

Reduce the weight of the suits to 5 kg when active.
-This way the medium and heavy suits can be feasibly worn by characters beyond Debug Hercules and STR+Weight CBM Cyborgs.

Set the hauling frame volume to 45 L.
-Like the suits it is very bulky to carry, but not to wear.

Reduce the hauling frame storage by 24 L and add two 12 L gun holsters.
-This gives the hauling frame combat value to counterbalance the generic storage buff of the suits.
