[WIP] Non reloadable tubes for USS Narwhal

[keltos01]

Right I had a couple thoughts on how to make those extra tubes non reloadable, and that should also work for the T-Class sub :

link the tubes to a new bunker with no ammo in the upc file

make a new entry in the zones.cfg with the bunker like "non-reloadable tubes"

any thoughts on this ?

I know in SH5 the rear tube in the Type VII is non-reloadable, as it was in RL.
