finish to hijack update loop + serialization

problem : tiles dont have an update loop, neither do they have a start / destroy method

solution : finished working on a way to create a custom start/update/destroy pipeline for the projects custom tiles. it's using LevelManagerScript as to Update.

note : also created a database and a start of serialization system so we can save and load stuff.
