Trading System (#43)

* Sanity checks + Starting level changes

- Item movement handler checks to make sure items aren't moved from equipment slot to equipment slot.
- Item give command checks to make sure an out of bounds item is not spawned (Below iType 0 or above iType 8)
- Players now begin at level 36, consequently the item give command does not level you up now.

* Initial Trade Implementation

* Taros and Trading

* working trading system

* Trading system code pointerified

- It works with the recent pointer changes needed.
