Improving TFS

[esfomeado]

In the last days i have been benchmarking/testing and analyzing the TFS source code and i have found some things that could be improved.

I consider this the main thing that could be improve on TFS.
Map Format:

Actual: Load all the map in the memory on startup
The main advantage of this is the speed of accessing the map.

New Format: Split in the map in chunks and loaded them into memory only when needed.

Advantages:

1. Really small memory usage
2. Faster server saves
   
3. You can buy cheaper VPS/Dedicated Servers because it will use lees recourses.
4. Others

Disadvantages:

1. Small performance decrease. (It will make no difference for players)

Other Improvements:

1. Stacked items aren't all a item and what i mean by this is if you have a stack of 100 gold you will have 100 items and this leads to a big memory waste because you could have only a item and say that item is actually 100 of them.
2. More ideias coming soon!
