Improved detailed item logging. There are still some ways to improve it even more but I think it isn't worth it.
At the moment if you drop/pick up items in the same tick they are grouped together in one entry due to the fact that the smallest time difference between two database entries is 1s (Timestamp value has an resolution of 1 sec) it would be possible to group all picked up/dropped item within one second to one entry.
Prepare the detailed item tables for the new item logging improvements.
