- The autoloot range check is no longer done unless AUTOLOOT_DISTANCE is defined (by default it is no longer defined)

- Ganbantein now deletes individual skill cells instead of the whole skill in the area it is casted.
- Modified the mob total damage code to prevent overflows when mobs receive over 2kM damage.
- Made the dmg structure of the damage log an unsigned int rather than signed.
