it's late..
add tile as dependency for objects
* Save all objects as list instead of huge 2d array
* Improve, bugfix and solidify object sorter
* Add rudimentary voxel bounds
Fix objects sorter creating cyclic dependencies when no proper distinction can be made between objects
Tigher SHP bounds used, resulting in less collisions/smaller dependency graph during sorting
SHP object sorting fixed
Added option for thumbnail generation with aspect ratio preserve option
support OnBridge for ownable objects
