IONCROSS gamedata corrections

[cshake]

Updates to gamedata_cargo.txt:

48 commodities were missing, full list would take up too much space here. Updated file attached.

I didn't know what description fit the following items, and just used the internal name as description:
commodity_textberne
commodity_bm_munitions

commodity_mox_rh - "MOX", right? but that's already defined, and what does the '_rh' add?
commodity_militaryvehicles_li - "Military Vehicles". again, already defined, and why the '_li' tag?

I know that these files aren't used too much, but I hope someone finds this useful somehow.

[edit] updated attached file with black market munitions [/edit]
