Duplicate categories are now marked instead of being listed multiple
times. This makes the configs far easier to maintain. Admins can still
expand each individual category for further customization.
TraderItemList and TraderCatList should be initialized as arrays, not numbers. Fixes this error:
```
Error in expression < 0;
if (_index < 0) exitWith {};
while {count TraderItemList < 1} do { sleep 1; >
Error position: <count TraderItemList < 1} do { sleep 1; >
Error count: Type Number, expected Array,Config entry

Tested buying and selling to all Stary and Bash traders as well as the boat dealer with these changes. No more error or problems.
