FCS Multiple ammo references on crossbows

[saftsuze]

I have been working on a couple of mods that include new ammo. Everything has worked as expected until I tried shooting. I could not get it to work even though my ammo was added to correct crossbows. After some testing, I found out that crossbows can't have more than one ammo listed. Would it be possible to be able to list more ammo on crossbows?
