Cargo Overhaul: Phase 1

-Ported Bay's cargo computer category system

-Created a box containing six flashes

-Crates have been tweaked significantly. Crates have been reduced to single item types where possible, namely with expensive crates such as weapons and armor. A total of 28 new crates have been added, including chemical and tracking implants, and raw materials can also be bought from cargo for a significant number of points (subject to change)
-Converted Bay's string based category system to a numerical flag system

-Fixed duplicated implant paths - thats what happens when you code until two in the morning

-Adjusted materials costs as follows:
50 Metal Sheets Cost: 10
20 Plasteel Sheets Cost: 30
