Long term serialization

[pampersrocker]

To save creatures in the long run without using up all available memory, dead creatures should be removed from memory and stored in a sqlite database for later data analysis.

[Zettymaster]

why not put all save data in there?! No akward multiple files to delete/copy if you want to make another run!

[pampersrocker]

For now a "graveyard" File is created which saves the current state of all Creatures died since the last save iteration. Tools may be created (a gravedigger :D ) to run queries on this created files.
