Cargo loading on SV

[SJuliez]

Fixes #5515

This removes code that tried to add cargo bays for F_CARGO equipment. I assume this was added to facilitate the internal bomb bay quirk. Cargo bays count towards weight and cannot be added in this way. I played around with this quite a bit and found that it was somewhat ineffective on units that can possibly have IBB (DS, SC, FWS, AF and CF). DS and SC do not use the that part of the code. F_CARGO is only on Cargo Containers (10t) and variable size cargo bays. For cargo bays, adding more cargo bays seems redundant (and didnt even work for a reason I couldn't see). For cargo containers, they seem not accessible to IBB with or without this code. I suppose we have to find another way to allow IBB in containers.

This makes a handful of SV canon units valid again, see #5509

Also (helpfully) adds transports to the output of DebugEntity.

LGTM. I'd guess that the F_CARGO block in BLKFile.java was a remnant I should have deleted after the ASF BLK file loader got it added.
